Re: [SlimDevices: Audiophiles] Which Interconnect Cable??

2007-07-19 Thread zanash

I have to say ...there is very little difference in sound between cheap
and expensive digital ic ,as there is between good and poor ones [note
the distiction]...

I've posted a simple design on the diy section thats as good as 90% on
the market ..at a fraction of the cost.

the only things that can help further are digital pulse transformers
and the elimination of signal bounce.  There are no true 75ohm rca type
plugs and sockets [regardless of the advertising].  If the impedance of
the cable is a mismatch the resulting bounced signal creates "echoes"
the reciever chip then has to try and retrieve the correct information
from the mish mash that arrives.

I've used the diy cable for about 10 years now with out finding
anything thats significantly better [thats affordable]

anyway thats my two pence worth !

That is the real question, not are measurements meaningful in the 
abstract, but what measurements are meaningful and which are voodoo.


This quote has been on my website's home page since I was in grad school 
working on a PhD in software measurement:

"When you can measure what you are speaking about, and express it in 
numbers, you know something about it; but when you cannot express it in 
numbers, your knowledge is of a meager and unsatisfactory kind. It may 
be the beginning of knowledge, but you have scarcely, in your thoughts, 
advanced to the stage of science."
 Popular Lectures and Addresses, Lord (William Thompson) Kelvin.

I believe a lot of the difference between "good stereo" and audiophile 
reflects meager and unsatisfactory knowledge.

Exactly. The ancient Fender Champ is legendary for great sound. It 
distorts like hell from 2 on up. But it sounds great. Clapton is said to 
have recorded the original Layla on one.  For my Strat and ES335, a 
solid state amp sucks. I've got a new Fender tube amp.

In the 70s, tube amps fell out of favor for hi-fi because the measured 
poorly and because transistor amps were more reliable. What was not 
talked about then, was that all tube amps are tone controls. Some more 
than others, but tube amps fail to meet the "wire with gain" ideal. So 
maybe it is not really so ideal.

My unfinished dissertation showed that in software, we don't measure the 
right things, don't know how to evaluate the measurements we get, and 
don't do the right things to fix it.

We are better in the audiophile world, but I don't think we are as good 
as we think.

Re: [SlimDevices: Audiophiles] Are measurements meaningful?

2007-07-19 Thread tyler_durden

Engineers use numbers to describe circuit behavior in an objective way. 
If you are the sort of person who doesn't believe in numbers,
measurements are meaningless.  If you are the sort of person who
believes numbers without questioning their relevance and the
methodology that was used to get them, they are meaningless.

Measurements are only meaningful to someone who understands what they
represent, which leaves out most people when you talk about audio and
other electronic measurements.

One thing is for sure "if there ain't no numbers, there ain't no
engineering!"  Think about that when you try to compare interconnect or
speaker cables.

I've always liked to think of myself as an objective subjectivist! 
Measurements -can- tell you important things about how a component
functions.  They can also point out differences that you cannot
possibly hear.  The real problem is deciding what the limits of
audibility are (and under what conditions). 

On the other hand, if you can demonstrate an audible difference that
isn't explained by your measurements, maybe you're not measuring the
right thing!

Or perhaps, perfect isn't what you like.  I've got an ancient single

Re: [SlimDevices: Audiophiles] Audiopraise product - will it really output SACD digitally?

2007-07-19 Thread DCtoDaylight

I don't think it's too difficult to convert between PCM and DSD or Vice
versa.  If I'm not mistaken, all the so called "Single Bit" CD DAC's
are performing a version of DSD.  But as Pat has said, it seems a bit
pointless given the low amount of SACD source material available.  And
the handful of SACD's I own all have a standard PCM CD layer, which is
what I've ripped for playback through my Slim system

Re: [SlimDevices: Audiophiles] Audiopraise product - will it really output SACD digitally?

2007-07-19 Thread Timothy Stockman

If you look at this page for Korg's MR-1000 DSD recorder, at the bottom
they talk about the DSF file format which supports DSD.  And,
interestingly enough, they state that some Sony VAIO computers support
the DSF format.  With a recorder such as the MR-1000 (and it's not the
only one), it seems like only a matter of time until SACD's
stranglehold on DSD comes to an end.  I don't see that it is completely
unthinkable that DSF couldn't become a reasonable format for
distributing high quality audio.  That said, I also agree that existing
PCM standards, such as 24/96 are probably plenty good for high quality
audio distribution.

For me the main reason for the functionality is to be able to move
through a podcast or radio programme to get the part I want to listen
to and using the current implementation on the SB makes it very hit or
miss. Fortunately it is more possible to do so via the web UI
implementation of AlienBBC although you unfortunately can't see how far
through the programme you are.

I agree though that the manual in no way correctly reflects the actual
ff/rw functionality.  That at least must be changed...

I read about it at audiocritic and in your thread here, and yes, I've
tried it.  After a particularly annoying discussion with the nutjobs
over at audio asylum I compared WAV to FLAC recorded at the analogue
outs of my SB3.  The difference was a file which consisted of nearly
white noise about 85 dB down from the signal (the noise was presumably
due to noise in the D->A->D, in the cables, etc.).  So the difference
between WAV and FLAC in my system at the SB3 outs is AT MOST a white
noise component 85 dB down.  Given that, with the amp set at
comfortable volumes for playing the original tracks, I could hear that
noise only with my ear a few inches from the tweeter, WAV and FLAC ar
identical.

I also compared two files with real differences to be sure it was works
- it does.  It's also extremely easy to use.

EDIT - Incidentally, I recorded this on my MacBook Pro laptop, a
windows desktop with a Soundblaster Audigy card, and with a Tascam USB
mic interface.  The windows noise was about 5 or 6dB higher than the
Mac, and wasn't exactly white (there were a few peaks).  Score one for
Apple.  The Tascam interface was terrible - it introduced an annoying
high-frequency noise component (which was audible not just in the
difference file, but in both recordings).

I agree, and am quite sure that you are right.  However, my ears are
what I listen to music with, so that is how I evaluate products related
to listening to music.  This seems reasonable to me.

I often get to a point in an A/B listening session where everything
sounds the same, at which time I grab a coffee and chill for a while. 
If there are differences I can normally hear them, often quickly but
sometimes less so, and if, over a few sessions, I really can't tell the
difference then I don't get fussed about it, buy the cheap or pretty
one.

Conversely, with difference testing there is all sorts of analysis you
have to do to prove the audibility of differences, and all you do is
prove the testing equipment rather than the music experience.  If you
find any difference, it gives you no indication of what is best, and if
you don't find a difference, the equipment might not be as sensitive as
your ears.  Pointless.

If you must be pedantic, it's the brain that sucks, not the ears.  The
ears are astonishingly good at picking up sound (although they are not
linear).  The brain is astonishingly good at doing whatever it thinks
it probably should, so it doesn't need to think!

And yes, this thread does deserve to be taken out of its zone... :)

Hi,
Thank you Harmonic for your explanation. Than my tiny little no idea
about hifi world is secure again I presume. ;) I agree with you. You
never got answer if the person actually tried the transporter as a
digital transport only.
I have two serious questions then:
1. What sort of amp is it, that you don't use transporter's analogue
stage if you actually have nothing to critisize about it's sound? How
much is such an amp? Or is it just setup determined?
2. How can such a difference occur in a digital only setup. Your amp is
doing the dac work right? Shouldn't a digital signal be a digital
signal? Or am I just a newb?
Yes I am! But perhaps you could share some ideas?
@ Phil : No I do only visit forums if I really want to learn something
very straight foreward. Time is rare and forums are often very complex
for speech outputs and braille displays.
What did you mean with your comment about people hearing what they want
to hear?
@ Tommy : I live in Germany and subsequently can not really listen to
the tp prior to buying one. So I try to get a glimpse of how the
community thinks about it.

To answer if it sounds very good straigt into power amsp the answer is
YEES.

Here in diddent have eny glassyness or glare at all  i was really
amazed by the sound no matter what i connected it to including icepower
amp,nuforce re 9 se v2 amps.

My main amp is a tact millennium mk3  this is basicly a dac   with
power.

What you do is simply connect  a trasnport straigt to it  and you have
music  no cd player or dac is needed.

it was in this system i compared the 2 TP`s   as dedicated transportes
feeding the millennium.

Now i cant answer you the questian if the mod will do eny good in your
system  because mine wassnt moded in the analog part and there for cant
comment on that .
But my gut feeling is it will.

thanks

difference. Folks my age, who had stereos in their dorm rooms got off 
the constant upgrade train.

Of course, I suspect that Phil has his tongue firmly planted in his 
cheek. But the measurement only approach is really what killed or at 
least strongly contributed to the death of Hi-Fi.

The problem is that some amps do sound different.
Measurements are part of the solution. I much prefer Stereophile's 
approach, measure and listen subjectively, over The Absolute Sound's
subjective only approach.

More directly to the old thread's "audiodiffmaker" measurement approach 
is that while it is wonderful at identical music, which by definition 
has to sound identical, it does nothing to explain why something is good 
  or bad if they are different.

Yes yes and double yes. Ears+brain=completly unreliable (ie subjective)
judge of anything. Comparing numbers=totally reliable.

The only magical thing about our ears is that they can't reliably do
anything.

Somthing that dossent seem to sink in was that i use the transporter as
transport only.

Meaning i connect the transporter to a dac via the digital output on
the transporter bypassing the analog section in the TP.

The transporter i have was moddified only in the digital part  not the
analog 
Meaning that if used as people normaly would meaning connecting it
straigh to power amps or there preamp it would not be superior to the
stock one.

The guy that keep saying that he heard no diffenrece  compared it in
setup where he used it as a normal player meanning it uses that dac and
analog part inside.

The person was so obssest in beleiving that the aberdeen transporter is
a froud that he never answered if he had tried using it as  a transport
only.

this is starting to anoye me but as transport only in was hands down 
much better then the stock one  the difference was massiv there  where
absolutly nothing to be uncerten about eny one that where here said the
same thing.


I  have had many  bad experinces with expensiv cables vs cheap one so
much that i must admit  that i think the whole cable industri is one
big froud.

If there had been even the slightes possibility that i had been wrong
with the improvment in the  transporters  i would never had spend this
much time defending it.

Remember very important i use it as transport only and there for cant
comment on the other skeptic users findings wich where using the analog
side also.
When that is said
I just thing its a sad shame that people dont just trie it for them
self  
in my system  the digital mod  was godsend when it removed all that i
diddent like about it stock one and im amazed that i listen to
unglarissh sound in a all digital system every time i listend.
No cable power conditioners or other tweaks can give you that.

thanks

Geeez I'm going to tell you something that must be very unpleasant
to a 'true' audiophile: Your ears are crap and with crap I mean really
crap. I mean as crap as crap can be and if your ears aren't that crappy

It's extremely relevant in this case: If there is no difference, then
there is NO difference!
The problem with a lot of 'true' audiophiles is that they just need a
justification for the large amounts of money they spend on their
equipment and that justification is their supposed superb hearing while
in reality probably 99.% of the 'true' audiophiles have as
crappy hearing as everyone else... maybe even worse...

Maybe there's something wrong with those tweeters?  Perhaps the ribbon
freezes up (or some other hi-jinx related to the cross-over levels
and/or sensitivity) when you do the 'pause' thing? Since they're

Hmm, good point.  I wonder - do you also find it easier to discern
differences with the volume on your amp turned all the way down?  Or
maybe you listen to your CDs by holding them very close to your ears? 
After all, the ear is a magical device that's far more accurate than
any electronic gear, right?  So why not remove the CD player and amp
and speakers - they just get in the way.

Look - audiodiffmaker is like turning up the volume on the differences
and turning down everything else.  Once it does that for you, you can
USE YOUR EARS to listen to the difference file - and guess what, the
differences are easier to hear, just like it's easier to hear louder
sounds than softer (at least for normal human beings with non-magical
ears), or to hear a quiet sound when there's no loud one to obscure it.
And if you want proof it reveals differences that the ear can't hear,
that's very easy.  Just take two identical files and run one through a
filter that distorts phase.  Totally inaudible (except in extreme
cases), but the difference file will reveal it easily.

It's been 22 pages of a thread. 

Omega is not going to provide here any useful info, except for bad
google marketing for SlimDevices and a bit of a rude reputation to some
SlimDevices personel.

If Omega had something solid in hand, he would already publish it.
SlimDevices, or anyone else on the forum with the equipment needed to
perform a test, can test it (with Omega flawed FLAC) and publish the
results. 

I at least, would then have no doubt nothing is 'bugg'. Otherwise this

It might, but why bother?
Not why think, civil discussions about audiophile stuff is fun.
But I don't see any point in DSD.

DSD has no proven sonic improvement over high-wide PCM. Sony claims good 
stuff, and the well done DSD I've heard sounds great. But DVD-A also 
sounds great. And well engineered RedBook can sound great -- even if it 
rarely does.

SACD has serious problems with noise shaping pushing digital noise into 
the 50mHz to 80Mhz band. Now granted it is above human hearing, but if
the ultra sonic bandwidth of DSD is important, why are they pushing the
noise so low? It has a huge potential for intermodulation distortion, 
which can be in the audible bands.

I don't see the point of using a plastic disk player connect to a 
Transporter. The whole idea is to never touch the silly disks again. Use 
a compute to manage and organize.

I have also not heard any difference between DSD output to my M-Audio 
Delta 1010, captured as 96/24 stereo, and simply feed to my Transporter.
Not double blind, but I don't see much science between Sony's claims 
that DSD is superior to MLP high-wide PCM.

Hi Guys or are there women out tere? :)
"Are there any good mods for transporter out there?" Was the simple
question that raised one of the dirtiest battles in a forum I have ever

concerned with making hopefully good audio devices.
The conflict got elicited by Harmonic who claimed to have a transporter
which was moded by Aberdeencomponents and consequently sounded far
better than the stock version. I really found the whole that as
unpleasant as interesting to read and I don't fency to open up the

A) in which setup Harmonic (who claimed that if connected to a power
amp via analogue output which he obviously didn't use to do) the
transporter sounded really good. I got you right Harmonic? What exactly

Re: [SlimDevices: Audiophiles] Audiophile wanna-be

2007-07-19 Thread Videodrome

I've been on both sides of the audio hobby:  As a junkie; and as a
dealer who sold stuff to other junkies to support their habit. 
What an interesting mix of people I met along the way!  

In the interest of trying to write a somewhat concise summary of what I
think being an audiophile SHOULD be about, I submit the following lists
for your consideration:

(1) When things are going right:

You have an operating system.
You're reasonably happy with how it sounds.
You enjoy listening to music, and you keep looking for new music.
You have a rich, meaningful life, complete with friends, spouse/S.O.,
family, etc.
You have other hobbies.
You don't spend all your disposable income on audio gear.
You know people will never understand why, unlike them, you're not
content with an boombox or an iPod, and you really don't care.


(2) When things are going awry:

"Your system's down," because:
You're never happy with it; and so
You're constantly buying / auditioning new gear to "get the sound
right."
You don't listen to much other than a handful of tracks on proven demo
CDs because you're perpetually evaluating gear.
You're a loner who spends most of your time hanging out in audio
stores, listening to gear (usually making snide remarks about how
unlike music it sounds) and/or at home, sitting in "the sweet spot"
listening to music by yourself -- in a dimly lit room.
You don't have any other hobbies (for the aforementioned reasons)
All you extra dough goes to gear.  Matter of fact, your '71 VW Bug
really needs a new radiator, but you blew $400 bucks on  silver
interconnects.
You can't believe (insert name of: friend, boss, family member )is
listening to that crap system, so you try to convert them.

Seconded. If musicians need to practise there are specialised machines

Re: [SlimDevices: Audiophiles] s/pdf SB better than s/pdf soundcard pc?

2007-07-19 Thread TiredLegs

In addition to my SB3, I also have in the same room a computer with an
S/PDIF output on the motherboard. Using an outboard DAC/headphone amp
(Grace m902) and high end headphones (Grado GS-1000), I queued up the
same playlist on both the SB3 and the PC (WinAmp) and switched the DAC
back and forth at random intervals over the course of an hour. I could
not hear any difference whatsoever. I mean, the sound was absolutely
identical as far as I could hear. Yeah, yeah, I know it wasn't double
blind, yada yada yada, but it satisfied me as a test.

On the other hand, before I bought both the SB3 and the PC with the
built-in S/PDIF (an ASUS motherboard), I tried to use the digital
output from an M-Audio 2496 sound card, but the card would occasionally
hiccup, resulting in annoying digital drop outs. The search for a better
way led me to purchase the SB3.

It's actually the other way around, i.e., the manual should reflect the
way the product operates. So if the manual is wrong, it needs
correction.

Regarding the FF/REW feature in question, I have owned CD players since
1984, and I can count on one hand the number of times I've ever used
FF/REW. While I agree that a feature to skip ahead or back ~X seconds
at a chunk would be useful to some users some of the time, it would be
about number 47 on my list of top 10 things Slim Devices engineers
should be working on.

P.S. Thanks Sean for a great explanation of the technical issues
involved.

Actually, in all likelihood (and I hate saying this because people tend
to interpret "could be" as "will be") Transporter could be made to play
DSD natively. It has a DSD-capable DAC, and there is programmable logic
interfacing the CPU to the DAC, and it can produce the right clock
frequency. But there is really no point because there is no DSD
material out there, except on SACDs, for which no feasible/legal
ripping mechanism currently exists.

Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?

2007-07-19 Thread opaqueice

This test takes two analogue audio signals and subtracts them.  The
resulting file is an upper bound on any difference - in other words any
real difference between the two files will be smaller than the result. 
You can then listen to the differences without anything masking them. 
You can turn up the volume, look at the waveform, etc.

It's an EXTREMELY sensitive test - much more so than human hearing in
an A/B comparison.  For example phase differences will show up very
clearly in the difference file even when they were totally inaudible in
the original sound.  If a negative result on this test doesn't convince
you, nothing will and there's no point in doing ANY test.  It's also
far easier to do than a proper blind test.

It's off topic, but you claim to have done blind tests for CDs versus
CDRs - can you describe the test setup and results in detail?

And the purpose of DSD was to maximize money that Sony gets, while 
cutting Philips, Toshiba, etc. out of the massive recurring money stream.

DSD requres totally new hardware for mixing, essentially obsolting

Then don't upgrade!

You can still use eq in iTunes if you feel the need, or go the extra
step and use the Inguz Digital Room Correction software. And then there
are hardware options as already pointed out above. I would keep the tone

I think tests like that will not result in showing a difference. But i
dont think that should say that the difference is not there and
therefor must be in the mind.

Because the difference between that cd and cdr looks like so much
simulair to this effect. And, as far as i know, there is also not a
technical explanation in difference between cd and cdr. Technicians
also say (and honnestly believe) that there IS no difference and all
the diffrence should be in the persons head... But with cd an cdr i can
prove the difference in blind testing, over and over again... But the
technicians still believe it is in my head...

But, escuse me for bringing this cd versus cdr back in this topic...
It's (probably) not connected to this problem... but as i say again,
those test will probably not result in differences, but... still it can
be there. We must know more about audio in technical way aand/or in
human-body way...

SACD players with DSD->PCM architecture are definitely out there.  In
the audiophile community, there are many that share your thoughts
regarding whether this defeats the purpose of DSD.  However, as I
remember, there is a European company that makes an S/PDIF transmitter
board which taps into a SACD player that already does DSD->PCM
conversion.  What these guys are saying about this new board is that it
has a custom DSD->PCM converter on-board that is better than any of the
standard DSD->PCM chips.  THAT is why they feel it is worth the high
price they are asking.

It would be interesting to be able to extract the audio from a SACD in
some hi-res form that the Transporter could understand.  If somehow one
could get the raw DSD data onto the hard drive, how would one use it? 
But converting to 24/96 would likely retain most of the sonic benefits
of DSD and could be decoded by a variety of existing devices, including
the Transporter.

Re: [SlimDevices: Audiophiles] Which Interconnect Cable??

2007-07-19 Thread opaqueice

You might want to read up a little on S/PDIF.  What you're saying about
error correction is valid for asynchronous digital transmission
standards such as TCP/IP.  However S/PDIF is synchronous - that is it's
sent at a steady rate in real time - and there is no error correction. 
Not only that, the fluctuations in the rate at which the bits arrive
can affect the analogue out, because most DACs reconstruct their clock
from the signal itself (so as to avoid under/overflow issues).  Jitter
in the arrival time of the bits can affect that clock even if there are
no bit errors, and that jitter will distort the sound by an amount which
can range from totally inaudible to subtle to awful.

On the other hand DACs are a mature technology, and modern and
well-desinged ones are extremely good at jitter rejection, so this is
probably irrelevant.

No, HDCD and DVD-A are both PCM. DSD, however, is a completely
different way to represent amplitudes. Instead of saying "make a step
this high", DSD says "turn the output on now, now, now, now, not now,
not now, now now, etc." Speaking DSD to the DAC is the whole point of
it. Now, that alone does not rule out the possibility that there is

Wouldn't DVD-A be another fundamentally different stream, which has to
be turned into something a DAC can understand? I would guess that it's
so manufacturers of SACD players can buy the software to decode the
DSD>PCM, just like they can for HDCD, and therefore wouldn't even need
to buy any SACD chips/hardware.

But lets say your player DOES do the conversion (as opposed to the
referenced company who is obviously feeling guilty!), and you're only
tapping an i2s stream. Since you don't have a DSD file on your HD, and
never hacked the DSD encryption, it doesn't seem too far removed from
the analog loophole to me.

Well, so much for keeping simple for the poor guy.  Yes, if one wants
to delve that deeply into the subject, every form of electronic
transmission uses modifications to the wave of the signal passing
through the transmission media/cable.  However, what we are referring
to is how those fluctuation's represent the data.  You sound very well
educated so I will just try to further explain what I meant to the
poster in case it incurred confusion.  I'll try to avoid explanations
of voltage vs. current, vs. frequency, etc.

Analogue (as used in home sound equipment)
When sound signal is sent from a player device, like a CD player, in an
analogue format, every sound frequency is represented by a matching
fluctuation in the electronic signal passing through the cable.  This
is the same type of signal that your speakers need to receive in the
end because speakers convert these exact fluctuations back into the
corresponding sounds.  

Because these each fluctuation exactly represents a sound
level/frequency, minor discrepancies in these fluctuations make a
difference.  This makes an analogue transmission much more susceptible
to any outside interference  or physical issues with the cable
itself..

Digital Signals (as used in home sound equipment)
When audio is recorded digitally, the process takes the analogue
signals from the microphones and converts each 'sound' (so to speak)
into a number.  The media stores these numerical representations of the
sounds. Exact duplicates of this recording can easily be reproduced
because you just have to duplicate the numbers.

When you play a CD and send out analogue signals, the numerical data on
the disk passes through a "DAC" or 'Digital to Analogue converter'.  The
transmission is then sent as described above.  However, if it is sent to
the receiver in digital format, it doesn't go through the DAC and the
exact numerical data is sent to the receiver.  It is then up to the
receiver's DAC to convert it to analogue before it hits the speakers.

Again, fluctuations in the electronic signal passing through the cable
are used to represent the numbers but..

-- There is some headroom in the levels of fluctuation before a number
actually gets misrepresented.  This makes it less sensitive to outside
interference to some degree.

-- The biggest reason why the sound quality is safer is that when
sending numbers digitally, something called error correction can be
used.  To over simplify, If the far end doesn't get 'mathematically,
what it expects to get, the data simply gets resent.  For tiny
discrepancies or loss, this happens fast enough that there is no
discernible sound loss or change.  Thus my statement that unless
something in the system is so bad that the sound data just doesn't get
there, the quality should be exactly the same for fiber or Coax.


Can Digital still go wrong?  Yes, but normally in a much different way.

--With Analogue, some physical properties of the cable (it's too thin
for the particular usage) and outside interferences can change the
nature of the sound you here.  This can cause you to hear changes in
sound quality, tone, static, hum, almost anything actually.

--With digital, normal circumstances result in an exact numerical copy
of the CD reaching the receiver.  However, a loose cable, a damaged
cable or even a cable bent too sharply can cause data loss.  This
usually causes jitter, chirps, or complete sound loss as opposed to
changed sound tone or quality.

Can the two sound very different even if both are working perfectly.
Yes, the thing to remember is that most modern receivers can run all
sorts of sound modifying modes on digital data.  Because it's numbers
and can be manipulated mathematically, you can do a lot more to the
sound than just adjust the bass and treble like on older receivers. 
This is why you will see many 'sound modes' listed on most receivers,
ie. stadium, club, rock, disco, etc.

Even if you feed the receivers with a plain old analogue signal, the
receiver can and might be converting that analogue signal to digital so
it can apply these 'modes' before reconverting it to analogue again to
hit the speakers.

One has to be conscious of all these things to make sure you are
comparing apples to apples.

So which is better, digital or analog?  
It can be a matter of personal choice but generally if you are playing
a CD or DVD or other digital media, a conversion from digital to
analogue has to happen somewhere before it hits the speakers.
-- Some would say that most DACs are created equal so best to have the
conversion done as close in the system to the speakers as possible
(normally meaning go digital from the player to the the receiver) to
avoid higher chances of signal modification or degredation.
-- Another camp might say, use the

This is the system I went to buy from my dealer, but was seduced into
upgrading the speakers to end of line Quad 11Ls and, more recently, a

Also, do invest in some decent leads, they really do make a difference.

Hi lars 

Its very simple just connect the interconnects between the outputs of

make sure the ouput is NOT set to fixed in the slim software otherwise
you will be deaf or dead when you press play.

The transporter just regulates its outputs with the volume control just

Yes i think i propably not going to hear any differance or have much
more difficult to distinguish between "good" and "Bad" sound.
Running through the analog outputs on the SB3 and removing the
"isolation transformers" & "power cleaners" (AC current 220V/50 HZ)


And if i remove my Elac CL 4Pi Plus (A universally applicable
omnidirectional tweeter) "Then my problems will ge gone".

I just tried to get a point in the previous post.
Not all people is running with an External DAC etc and probably and not
hearing this effect.

Or as you wrote in the previous post:
"My system isn't very high-end at all, so it could possibly have been
masked in the "digital out-->analog conversion-->speakers-->room
effects" chain but I doubt that. "

Re: [SlimDevices: Audiophiles] Transporter together with Nuforce amp?

2007-07-19 Thread larss

I have just ordered a Transporter to be used with my Labtop and would
like to use the Transporter balanced XLR directly to the Nuforce 9SE
Reference.

How to contro the volume without using any preamp.?

How does the Vpp output from the Transporter correspond to the
requirement from Nuforce, any problem here?

Re: [SlimDevices: Audiophiles] Amps without tone controls

2007-07-19 Thread Ashy72

I Own a pioneer A400X (audiophile) amplifier fairly old now however,
this amp does not have bass or treble controls. This amp sounds quite
bright in the treble end and has a nice bass at the low end. As someone
else mentioned, you actually hear the music as was intended by the
recording engineer. I have never missed my bass /treble controls and i
have never thought about getting a graphic equaliser. I just want pure
clean signal. I think the only way to be sure about what you are buying
is to go to a dealer with a sound  room and listen for yourself, you may
be very surprised.

I think that the nuforce amsp will work wonderfully with your strauss.
I have heard them several off times and the are fantastic.

The nuforce amps will diffently grab them by the nuts and give you all
the slam and power youwill ever need.
The are also extremly detajled wich will work grat with the scan speak
softdome tweeter in your strass.

The Transporter have the fidility and kvality sound to not make the
nuforce sound glarish.

(I've heard something about setting a DIP switch inside the Transporter
if used as a pre-amp, anyone?)

regarding this  im all ears but  i just hooked it up to power amps and
it worked flawlesly .

Hi 

Its a tact millennium mk3 its basicly the same as the lyngdorf mk4  but
this one has been moddified to the ninth degree
Besides what ever people have to say about anthony his work on tact
gear is hands down magical.
Not that it matters much but it dos also cost a 3 times as much as the
nuforce amps.

But this issent about tact its about nuforce yes the delaer explaind to
me this was the brand new top model ref special edition V2 amps and had
been running for a roun 150 houres.

One thing thats more important then enythig else is  that we all have
different preferences .
See for me the highnnotes  in a system is what most importeent also
that the sound must be as clean and unglarish as possible without
offering the solid state superioties and here the modded millennium  is
the absolut champ.

The nuforce v2 ref 9 se are the champs with dynamics and bass.
If the are paired with the right speakers and gear you migt very well
get system synagi.

I extensivly listend to the nuforce amsp (and yes it was the new v2
amps) 3 different days at a dealer the first day with his frontend ,
the sound where very glarish but still impressiv.

The next day i brougt my transporter form aberdeen components and wee
hooked it straight up to the nuforce amsp the sound was MUCH MUCH
better no glar  more dynamic more forcused soundstage  the dealer
ordered 3 transporters the same day.

The third day he had installed some new caps in his speakers and the
whole thing sounded better the ever before.

What this is telleing me is that the nuforce amsp are transperant amps
and there for will be revaling to the upstream gear and that the
transporter is on hell of a packets deal and it dos work very well with
nuforce amps.

thanks

Harmonic, 

That's quite a statement...the Tact Millenium is a top amp but beating
the rest by a wide margin?! Which version of the Millenium have you? As
for Aberdeen components, sure he knows everything that there is to know,
better than the designers themselves ;) I am not saying his mods dont
work...but he claims too much...

I tried many different power amps in my system, Class A, Class D,
Valve. I am happy to use the Nuforce as part of my reference system.

Have you actually heard the Ref9SE v2 or v1? There is a big difference
between the two.

I agree that preamps will steal a bit of the dymanics.

I also agree with the speaker choice.

Regards,

Greg.

Re: [SlimDevices: Audiophiles] budget system help

2007-07-19 Thread zanash

if you can indicate the budget.more precisely.

from my experience 

t-amp fantastic imaging ...but no bass bellow 100hz has only 3 watts
usable power before clipping.
nad amps ...are only warm if you use the fitted vol potsthey can be
clean fast dynamic if you use an alps blue [this was true for my nad
3020a anyway].
richer sounds..gear 
the cambridge azur 740 amps are very good. the a1 and a5 are ok 
speakers ...the kef q7 and the tannoy eyris would be [on paper] the
ones I'd look at...but you need to listen to them preferabley in you
own listening room.

What's to learn?  You already have a very nice system.  Enjoy it.

Or, you can spend ungodly amounts of time and money seeking
increasingly tiny improvements, driving yourself broke and bonkers in
the process, and not really enjoying the music as much because you're
constantly twiddling with the system or dreaming about the next tiny
improvement and how to pay for it.

I've always been happy with NAD amps.  They sound very good for the
money and tend to work well in lower and mid-priced systems.  I'd
classify their sound as "warm and dynamic".

Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?

2007-07-19 Thread danielu

To Omega & co

First I most tell all, I do not have a SB3 so I not able to hear how it
sounds and I not able to verify your clam. 
But as I see/read it, you and your friend have both a heavy modified
SB3. This it self could be a problem as you not able to conclude that
is the SB3 that has the fault. You also report that you think that
without a isolation transforms, filters and so on  you would have
difficulty hearing the difference. Please do this test as a blind test
for another person the you self/friend, this should be easy. And report
back you discovery.


In your setup, how can you be sure that there isn't a part of the 
system that falls, it could be that it just can't stand to have the
same piece of music played twice with out a power off. It could be that
the DAC have going in saturation/fault mode or soo 

In the pause situation not power off. 
The electrons could be jammed in the cables you could try to change
them all.


To all please don't take this selection very seriously :-)
I not a believer

Maybe Sean can answer this; during a power off situation are any
part/circuits of the SB3 actual power off. I thinking in the non audio
part, display control, wireless interface, main cpu and so.
and in what state, are these circuits in a pause situation? 
It could be that something could add noise or change the phase in the
music signal after a pause in the audio signal.



All test should be blind tests:

What happens is the first track played last a fraction of a second how
it the next track then perceive?

Try during the first good track to power off and on various parts of
your soundsystem, DAC, preamp, poweramp. what is the   perceive sound
like

Do you have the possibility to use another source to your extremal DAC
like a cd player? Then try the same test.

What happens if you use a pure tone instead of music? try both a high
and low frequency tone 

My biggest concern is that you stop/have a break in the music. To my
knowledge this alone can be enough for some to report that the heired
two sounds (this is in a pure tone test).  

I can only suggestion you make a recording of the two situations and
publish the result to this forum. 


My last comment please accept, that some people can't hear what you
hear. if your not sadified with the SB3 buy another product rebuild it
like others have. Maybe this product is just not high-end enough for
your ears.  

regards
Daniel

Re: [SlimDevices: Audiophiles] Audiophile wanna-be

2007-07-19 Thread mudlark

Make a nuisance of yourself by visiting audiodphile dealers and
listening to their advice.

Try to buy something from them as its an expensive business being an
audiophile dealer.

Read lots of magazines.

To be a real audiophile try listening to your music rather than your
system.

Visit lots of websites,

After a couple of months you can either

1. Listen to some music.

2. Drive yourself mad trying to make your system turn the listening
experience into a mind changing delight.

Please note there are lots of nice people in the audiophile world, but
also a lot of nutters. (respect to normal nutters) who are annoying
little bores who should have a spiky audiophile amplifier shuvved where
the sun don't shine.

Maintain a sense of reality and keep a sense of humour.

PS Don't mention power supplies, DACs, in any posts.

:D
