I too think you should get better speakers. I understand your reluctance
since you recently bought your other speakers but 1,000.00 will buy you
some very nice speakers that will make a much bigger improvement in
your system than the Benchmark.

The diference between good 1,000.00 speakers and what you have is MUCH
greater than the diference between the Benchmark and SB3 DAC.

Re: [SlimDevices: Audiophiles] Million dollars to prove cables areworth money

2007-10-12 Thread musiklov3r

I'm curious as to exactly what tests an engineer would enact to compare
two cables.  What specific measurements would be taken?  Are these
tests complete enough to truly be able to replicate all of the elements
involved in our hearing?

I'm reminded of the many debates that have been posted on this forum
about jitter.  If I remember correctly, someone posted that the ability
to test for jitter and in fact even the comprehension of the possibility
of such a phenomenon did not occur until sometime after digital audio
was created.  

During this time period did people argue about the sound of one
converter vs another?  If jitter was introduced into the signal path
(let's assume there was some sort of cause without getting caught up in
this detail) and was more prevalent in one design than another, it would
not have shown up in any tests during that time period.  Without a test
or a term for the difference in sound quality between the two units, an
argument could be made in a forum that if they had similar measurements
there should be no sonic difference between the two units.

Again, I'm not saying anything about the 7k cable.  I have no idea of
it's value or sonic impact.  But with regard to the ability to measure
the impact of one cable versus another, is it possible that we have not
yet identified the qualifying variable and as a result have not come up
with an appropriate test?

Food for thought?  Maybe I'm way off base.  It's late this evening...

I'm a big fan of getting the digital source right, more than most on

from spending on your front end in such a system.

I guess that if you see the next couple of years being spent gradually
upgrading your hifi, then it could make sense, but to be honest that's
not a particularly rewarding process.  Spend half the money on music,
save the rest, and splurge out on a big upgrade in three years. 
Spending smaller amounts on a fairly well-balanced system is often more

Let's try to explain it:

we have cable A and cable B. They both have different physical
characteristics, so they could sound different, that's what we want to
proof.
We hook 'm up between an amplifier and some speakers.
We put a microphone somewhere in front of the speakers.
This microphone registers everything which is coming out of the
speakers.
We compare the signals produced with cable A with the signals produced
with cable B.
As the cables are the only changing part, if there is a difference, the
cables will be the source of the difference.
In this case they match completely.
Now tell me: where does the brain have any influence on the signal of
the cables other than the placebo effect?
You're not hooked up to the cable (at least I haven't seen anyone yet
with plugs in his head...)
Another way to test it would be to check the signal right after it
enters the speakers, if the signals are the same, the speakers won't
sound different...
Or do you guys have intelligent speakers that think:
Wow, I now have superduper expensive cables, I'm getting the same
signal but let's start dancing so that the 'audiophile' in front of us
gets a reason to rectify his/her purchase...

 @adamSlim,
 maybe, the microphones aren't perfect, but that's the case for both
 tests (cable A and B)
 and that also would be eliminated if you go for option B (comparing the
 signal at the entrance of the speakers), but ofcourse there will be some
 invisible elves who enhance your hearing when you use the superduper
 expensive cables... whatever, if it gives you a comfortable feeling...

You are still missing the point.  If I have two identical cardboard
boxes, one filled with gold and the other with lead, and the measuring
device available to me is a camera, the boxes measure equally. 
Obviously, they are not equal in a relevant way, but my measurement
system is not sophisticated enough to detect it.

It is certainly likely that there are limits to our current
measurements for audio, so some relevant difference could be
undetectable by those measurements.

In practical terms, you may be correct.  Perhaps there are no
limitations in our measurement technology that can account for
meaningful, audible differences.  However, the possibility clearly
exists.

Intellectually, I do favor double-blind testing.  If someone can tell
the difference in a well-constructed, double-blind test, then it exists
(statistically speaking).  If your instruments cannot measure a
difference, then it is a limitation of your instruments.  If they can,
then perhaps that difference explains the difference in human
perception, but perhaps it is something else that your instruments
cannot detect.

In no one can tell the difference in a well-constructed, double-blind
test, then for all practical purposes the difference does not exist. 
If your instruments can measure a difference, then it must be a
difference that is not audible.  If they cannot, fine, but they still
may be limited in detecting factors that are not audible.  

Finally, I am very skeptical regarding mega-expensive cables, and I can
think of virtually no circumstance under which I would value them given
their cost.

2007-10-12 Thread musiklov3r

If I had to guess at what the difference is between a better performing
cable and an inferior cable,  for instance the Belden 1800f vs Monster
cable or Whirlwind as the inferior cable, it would be a combination of
frequency response and distortion.  The more accurate the playback
equipment and room, the more influential small amounts of distortion or
frequency irregularities will impact the overall sound.

What I have found as that I have upgraded my system, new flaws that
were imperceptible (or masked by bigger problems) before are found and
become more difficult to solve.  For instance, upgrading to a more
expensive cd player or DAC like the SB3 to the Transporter is a fairly
easy change to make, it just requires additional funds and the
knowledge or experimentation to determine which of the more expensive
CD units are worth it.  Some companies are marketing based, others are
engineering based and if I'm spending a large amount of money on audio
gear, I'd rather buy one where the funds have gone into engineering. 
However, once you have high performance from your amps, speakers, and
source, and improved room acoustics, the cabling and power while making
less noticeable or less cost efficient differences in the beginning, now
must be focused on to improve the level of the system.

Just as acousticians discuss improving the acoustics so that the room
can handle higher levels of spl without adding acoustic distortion, as
you listen at higher volumes the impact of distortion and coloration by
cables becomes readily apparent.  

I'm not familiar with the measurements for distortion.  Can they
measure the full frequency spectrum?  If there is an analog form of
jitter induced by cabling that increases harshness on transients and
clouds the audio information by creating random electronic micro-echoes
of the signal due to timing irregularities of the signal, would this be
measured by today's distortion test?

I'd like to volunteer my system for testing if anyone else in the San
Francisco Bay Area would like to conduct these electrical tests or even
double blind testing.

The ATC speakers I use are known for their exceptionally low distortion
and uniquely precise accuracy and imaging, among other engineering
advances, and are used by top mastering engineers, recording engineers,
movie scoring stages, composers, and performers.  I'm including this as
both a shameless plug (I'm in the process of opening a showroom) and
because I think they are unique at highlighting sonic differences in
things like cables.  Speakers are only as good as the information you
feed them and the room they are in, and you will never be able to hear
what your speakers can't recreate accurately.

 You are correct about data being handled without error on computers. If
 in the very rare case there is an error some part of the system crashes!
 Information Technology is based on error detection and correction,
 buffering and asynchronous transfer. This differs from the audio world
 where things tend to be synchronous and therefore less than reliable,
 and it's not obvious when there is a problem.

But there is error correction in digital sound technology, too, isn't
there?


darrenyeats;234105 Wrote: 
 The only areas of debate are where signals get converted into numbers
 (recording, mastering, ADC) and where the numbers get converted into

 that lossless formats like FLAC describe the same information as CD or
 WAV.

But the OP's question was about the digital domain. He was asking why
his DAC sounds different when it receives a stream of numbers from his

streams of numbers are different. Surely we can all accept that. Either
the difference is in the digital or the psychological domain.

darrenyeats;234105 Wrote:

I think, Darren, that you might be looking for problems where they
don't exist. Banks have networks, and RFI, but they don't lose bits,
why should music equipment lose bits? Networking systems are robust -
what goes in comes out.

I'm surprised that this discussion has got this far without anyone
mentioning jitter, which usually sends eveyone running for cover. If I
can store software and recover it, and trust my bank statement, surely
storing digital music and recovering it is a doddle. The technology is
mature and there is huge and effective error correction where it is
needed.

'Golden eared' hi-fi enthusiasts often tend to report differences they
'hear' as simple fact, like saying 'I looked out of the window and it
was raining', without taking into account their subjectivity, what side
of bed they got out of that day, etc, etc and without expressing any
hesitancy or doubt about their opinions, or recognizing that they are
trying to detect very tiny phenomena. I suspect that many reported
differences are psycohological rather than actual. Surely many of us

Re: [SlimDevices: Audiophiles] SB3 digital output quality

2007-10-12 Thread apeman

the thing that trips up so many technical people when thinking about
data is that if the bits are transmitted without error (or with errors
corrected), that you cannot have an audible difference.  but what is so
often overlooked is that, unlike copying a computer file from a CD to a
hard-drive, audio data requires precise timing of delivery.  your file
copy doesn't care if the bits come at a rate that varies slightly or
greatly -- it can afford to wait until the bits arrive, and write them
to the destination drive.  but in audio, the bits represent the
amplitude of the signal at a certain point in time -- so if you get the
amplitude perfectly right, but the point in time slightly wrong, it's as
if you got the amplitude slightly wrong (because the original signal
would likely have been slightly different at a slightly different point
in time).  and of course, *how* different it would be is a function of
frequency -- lower frequencies will be less wrong, higher ones more
wrong.  

so that is why it is a fallacy to only talk about whether the bits are
transmitted with errors, because audio bits are different from file
bits or web page bits in that their precise timing is required to allow
them to properly represen the original signal.

the saving grace is that if you *know* what the timing is supposed to
be apriori (i.e., it is the sampling rate), then you can get past the
timin errors by buffering the bits, and play them back at the right
sampling rate -- that's what accessories like the monarchy DIP do.  my
SB is connected to a monarchy DIP before hitting the DAC, and it
sweetens and smooths the treble to a welcome (if subtle) degree.

i.e. 1) are the bits being changed en-route? 2) are the right bits
getting to the DAC, but not at the right time?

to test for bitstream corruption, take a DTS encoded audio disc (e.g.,
the moodys blues days of future past) and rip one track to a WAV
file, just like you'd rip a normal CD track to a WAV file.  play that
thru the squeezebox, and run the S/PDIF output from the squeezebox to
an A/V receiver that recognizes a DTS bitstream.  WARNING - TURN THE
VOLUME CONTROL WAY DOWN FIRST!!!  if you get a correctly decode DTS
bitstream, you'll hear music, and can conclude that the bitstream is
intact.  if you get white noise at a loud level (which is why you must
turn the volumn down first), somewhere along the way the bits are being
changed.  in my experience, any change to them will be audible as
degradation, usually a a muddying quality, felt most as adding edginess
to the treble.

but if the bits are intact, it would be down to jitter.  a jitter
reducer (like the monarch DIP classic) can be beneficial to clean
things up, because it re-clocks the bitstream prior to sending it to
the DAC.  also, different digital interconnect cables can effect
jitter.  and the RCA S/PDIF output will likely have lower jitter than
the toslink output.

hope that helps...

Re: [SlimDevices: Audiophiles] Million dollars to provecables areworth money

2007-10-12 Thread Phil Leigh

Here's a test:

start with a CD track - so we know exactly what the bits are. put
through a good DAC and analogue interconnects to a suitable high
quality and calibrated ADC - record the bits. Compare the recorded bits
with the original bits. Any change must be induced by the cable. Repeat
with endless cables - analyze the results.
I'd expect to find that some cables changed the sound and some
didn't...
Anyone care to try this? (I don't have a suitable ADC anymore or I'd do
it myself)

The benchmark would be with the DAC and ADC hard-wired with no
intervening cable...

[SlimDevices: Audiophiles] Integrated amp versus active speakers

2007-10-12 Thread jaysung

Hello,
I know we have had it over and over again and even worse the general
point seems to be clear. How would it look for my special case then:
I have:
- transporter via xlr into
- Marantz PM-11s1 via Bluematrix copper cables into
- 2 x Dali Helicon 400
---
Since the Marantz is an integrated amp I keep thinking about replacing
it with just two mono power amps.
Or even more consequent: Replace speakers and amp with active speakers
in the same budget.
Now some questions:
1. If I just have mono power amps or active speakers how is volume
control managed then? 
2. Do those mono blocks run hotter, louder or in any way more eneergy
hungry?
3. I am quite satisfied with the setup actually. Will there be lots of
improvement in terms of transparent play? If I stick to the same
financial frame.
4. Would bi-wiring my current setup bring about signifficant results?
5. Any concrete recommendations?

Thanks as always
Jeronimo

Re: [SlimDevices: Audiophiles] Integrated amp versus active speakers

2007-10-12 Thread musiklov3r

I think Adam's comment makes a lot of sense.  If you are not feeling
like something needs to be improved and aren't haunted by something
else that you have heard, you might just be in a perfect place to
really enjoy your music collection and add to it.  There is always
something better, but if I could go back in time and not be exposed to
better sound systems, I'd be enjoying my old system and would have a
lot more money...and perhaps be just as happy.  Reminds me of Pandora's
box.

One positive for active speakers is that the manufacturer has matched
the amplifier to the speaker and possibly put the crossover before the
amplifiers so that the amplifiers are operating in a more efficient
manner.  IMHO I think this lends itself to a better cost to value ratio
than finding your own amp to match.

The Transporter makes a fantastic pre-amp to drive an amplifier or
active speakers directly, and a dedicated preamp that would surpass the
performance of this setup is extremely expensive, so I think you are
focusing on the right areas.  You might also want to review your
acoustics and see if minor, inexpensive changes might increase your
performance more than the other upgrades you mentioned.


Transporter - ATC SCA2 - ATC SCM100ASLT

Actually it's not a bad idea.  What you both seem to be missing is that
everything we listen to over an audio system has already passed through
a microphone at some point (except some electronic music).  If mics
have major imperfections that distort sound those imperfections are
already present in the recording.

Of course what's more direct is simply to do cable a listening test. 
But wait - that's been done many times, and no one can distinguish
reasonably decent cables from each other unless they can see them! 
What a shock - extremely sensitive measurements indicate that cables
are nearly identical, hearing tests indicate that they are identical,
physics theory tells us they should be very very similar...  and the
only argument on the other side is the opinions of some cable
manufacturers and a few neurotic audiophiles?

Why are we still discussing this?

with what Sean says about it being best to have the -ve unconnected.

So...

As I said up front, my preference would be to stick with my current

If (as you suggest) nearly all adapters DO have the -ve unconnected
then there won't be an issue, but that is the question I would need a

If speakers vary most in presentation and SQ, as opposed to source and

like it with current speakers and then when money allows pick from the
huge range of different sounding speakers to get exactly what your

Rather than speakers 1st (with current kit) and then later try and
choose from a smaller choice of different sounding sources to get

I haven't posted here before (just passing through because
squeezenetwork is on the blink), but I thought I would add my
experience to the thread.  Friends (not audiophiles, and highly
skeptical) and I blind tested (not double blind)a squeezebox vs. a
Bolder modified (digital only) squeezebox.  The rest of the digital
processing system is a Behringer Deq 2496, into a Lavry da10.  The
power supply was a Bolder modified Elpac.  All of us could hear a
significant difference:  the Bolder modified squeezebox was better. 
One non-audiophile friend called the Bolder modified squeezebox
brighter.  I would say it was clearer and the background was
blacker--the grunge was removed.  We also briefly tested the Bolder
modified squeezebox as a source vs. a Marantz 8260's digital out (i.e.
using the Marantz as a transport).  Again a difference: the Bolder
modified squeezebox was better--it had better control of the bass--a
cleaner sound.  So, yes, the transport matters.  Frankly, I was
surprised by the degree of difference.  By the way, we also tested the
coax (Blue Jean Cable) out of the Bolder modified squeezebox vs. the
optical out using a cheap BestBuy quality Toslink.  I was surprised to
find the Toslink was better--again it cleaned up some grunge (I presume
RFI/EMI is the culprit)--instruments and voices had more body.  FWIW

Feynman's QED is a pleasant afternoon read for anyone with just a
little background (say a semester of college physics or a good high

the main points across rather effectively.  You're not going to master
quantum field theory without knowing a fair bit of calculus, but you
can get a reasonably broad understanding of many of the important
concepts in quantum mechanics.

It's quite accurate and insightful, unlike many popular science books
that just give the reader some buzzwords to spout at cocktail parties.

It's also incredibly well-written.

Denny,

The timing does matter here.  The same bits with different timing can
yield different audio output.  Jitter does exist, although one can
argue about its significance.

If you read up on the SPDIF protocol and understand how the clock is
obtained from the data signal itself, you will see that it is indeed
different from moving a data file across a network.

- and then ...

Yep, good point made on active speakers: Where are the croos over
networks located. Before or after the amp. Cause if they would be after
the amp I wouldn't quite see the point since then you basically should
have shuffled the place where cabling is done. Either way you got to
connect the tp to amps and those to drivers in any form. In you fit amp
and drivers in one box the cable from the tp will be longer since you
want to have the two speakers well apart. In my current setup on the
other hand I have got short xlr and rather longish copper wires to the
speakers.
Volume control only via transporter? But then the amps would need to
always amplify as much as they can since they themselves didn't have
any measurement to decide for the volume. Wouldn't that mean that they
add to energy comsumption and possibly distortion?

speaker lines as there is less potential for interference due to the
balanced design and interconnects are usually cheaper than speaker
cable. 

With regard to amplification, Class A is considered to be the premium
analog amplifier design while Class D stands for digital amplification.


I don't believe that you will increase the distortion or power
consumption by using an amplifier in an active speaker.  While it is
true that the amps will be at full volume, typically this is done in a
separates setup anyway.  The amps are at full power and the pre-amp
is used to control the volume.  Currently you are using an integrated
pre-amp and amplifier which with regard to sound quality is considered
inferior to having the amps and pre-amp separated.  So to get to the
next level of amplifier/pre-amplifier performance you would be faced
with the power consumption issue either way.  Hopefully someone can
educate us as to the power consumption of amplifiers.  I don't believe
they consume as much left on with low volume playback or with nothing
on compared to playback at full volume.

Hope this helps,

Will

It is true that many audiophiles assume that Class A is better than
Class B, but this is not high school grading.

The term refers to the circuit topology, how it addresses analog signals.

Class A amps use a single amp to handle both the postitive and negative
portions of the sine wave. All audio is sine waves. This is very
inefficient. Class A amps (preamps, etc.) draw large amounts of power
when there is no signal,

Class B amps split the sine wave into two parts, negative and postitive.
They then amplify them separately, with one half doing positive 0 to X
and the other half doing negative 0 to -X. The signals are combined for
full wave. This means that when there is no signal, the amp does not
amplify anything.

Many audiophile amps are Class AB, which run as Class A for low signals
and switch to Class B for more power. They attempt to get the simple
circuit of the Class A without the evil energy waste of a Class A.

It is extremely rare to find a Class A amp that puts out more than 20 watts.

The marketing departments of companies selling Class A amps like to
claim that they are best. But its not clear. Good Class B amps can be
better than Class A amps.

Thanks for the kind offer, Sean. (And sorry for the slow response -- got
swamped at work.)

I had the send the silver Bryston integrated back, so now I can keep
shopping for a black amp to match the Transporter.

If you don't mind me asking, what happened with the Bryston?

I wouldn't say exactly rare.  Atma-Sphere's tube amps start at 30W. :)

Re: [SlimDevices: Audiophiles] Integrated amp versus active speakers

2007-10-12 Thread pablolie

I have become ahuge believer in the future potential of simplicity and
stuff like SB + active speakers. 

I am amazed by the price-performance ratio of the SB3-Audioengine5
combo. As people are probably getting tired of hearing, I have
temporarily moved from my (larger) home to a studio apartment.

In my home, I have been listening to music through a high end Accuphase
chain feeding into artesan German speakers tweaked by a renowned
audiolab. It is not an esoteric $100k+ system, but it is pretty nice,
and has received plenty of acolades from fellow enthusiasts.

So when I moved, knowing I could not be without music, and knowing I
could not take my system, I was worried.

Here I am, one month into this. The Audioengine 5s are probably still
not entirely broken in, but it is amazing how musical and detailed they
are. At a fraction of the price of my home stereo. The SB3 holds no
surprises, I have been a hige fan since I bought one in January 06, and
by now have 2 of them. 

I think the future belongs to the simple streamer-into-active-speakers
concept. really. Elegant, simple, nice to look at, and very balanced at
a fraction of the price. Wow.

I am not yet done evaluating, I shall do so in a few weeks. But suffice
to say: while I do miss my home system, I thoroughly enjoy and am
incredibly grateful I get to enjoy the simple system I now use while
away - it's a lifesaver, and an eye-opener.

The high end audio game will tip that way.
