Re: [SlimDevices: Audiophiles] Direct connection to PC

2007-07-03 Thread Colin Reilly

Thanks for the replies.  I understand how data works, I just wasn't sure
if the extra connection might make any difference, but it makes sense.

My music server is plugged into a wired router along with the SB3. 
That is all that is on that network.  I have a separate wireless
network for my computers.  I had the SB3 on my computer network, but it
kept dropping out due to the fact that there were two hops involved and
the wireless router was in the basement, so I wired it to the other
router and it now works perfectly.

Just mulling things over guys.  I'm always looking for ways to improve
the sound quality.

I didn't understand why I must use a balanced XLR cable and not the RCA
one?

If I need a passive resistor pack, why shouldn't I use the attenuation
inside the Transporter?

You should be able to use the balanced XLR cables without any analog
attenuation at all if your listening volume control is > 1/4 of the
volume bar on the transporter.  If you can't get above 1/4 volume on
the transporter, you will need a passive resistor pack between them.

I tested my transporter with an Atma-Sphere amp a while ago..

I powered everything off and connected XLR cables.

I turned on the transporter and turned the volume control all the way
down.

I powered on the Atma-Sphere amp's tube warmers.  Then I turned the amp
section to on.

I then started playing a track that would start out quiet, seemed ok,
so I started turning up the volume when the VU meters were bouncing.

We hit a low listening level around 1/2 volume, and a normal listening
level around 3/4 volume.

It was a perfect match. :)

Yes, if you do it that way, you won't be able to use Squeezenetwork
unless your PC is on.   It also complicates your network setup (now
your PC is on two networks and needs to route).

It would make zero difference in sound quality.  Ethernet is not an
audio cable.  Data is sent in packets, each with error checking, and
retransmitted until it is correct.  You will see this with a hub,
switch, router or cable... it will behave the same way. 

But not using a hub means you will need to figure out routing on the PC
so that you can listen to anything other than local music.

No, it will make zero difference.
Wiring direct rather than using WiFi can improve the sound, especially 
if you are using 802.11b rather than faster 802.11g, but its usually 
binary, you get dropouts or evil things if the link is not good enough,
so when the sound is working, changing the network is not going to 
"improve" the quality.

Re: [SlimDevices: Audiophiles] SB vs SB+ vs Transporter as transports

2007-07-03 Thread GaryG

Guys

I've tried the following kit in various combinations:
Empirical Audio Off-Ramp Turbo usb/spdif converter
SB3
SB+
Transporter
Meridian 200 Transport
Meridian 500 Transport
Meridian G98 DVD/Transport
Meridian 602 Transport
Wadia 270 Transport
Meridian 203 DAC
Meridian 566 DAC
Audio Synthesis DAX Decade (Black Gate) DAC
Audio Synthesis DAX Discrete (Black Gate) DAC
Wadia 27ix DAC (Black Gate)
Meridian 568.2 Processor
Meridian 861 Processor
Theta DaVid
Tag DVD32FLR
Wadia 861se with GNSC 'Statement' mods
Meridian 518 (re-clocker mode)
Big Ben (re-clocker)
Tact RCS 

Knowing what I know now, if I was on a low budget I would buy an SB3.
If I had a bigger budget and lived in the UK I would buy an SB+, it's
performance is incredible for the money, the best DAC in my list above
was the GNSC Wadia 861se digital input and the SB+ was better than an
SB3 with the 861se. If I had a bigger budget and lived in the US then
I'd consider a Transporter, especially with mods.

In terms of just a digital transport the order of performance is as
follows:
Transporter
SB+
SB3
In terms of outright performance I was unable to match the performance
of the SB+ or modified Transporter analogue outputs when using any of
them with an external DAC despite using fancy digital leads (£400 each)
and re-clockers.

My Transporter was originally shipped to Wayne at Bolder Cables for
modification but after nearly 4 months of R&D on Transporters Wayne
didn't feel he could better his SB3 mods so I had it sent to Reference
Audio Mods who did their top-end mod plus some additions I suggested.
Since then I've done some further mods on it myself.

Gary

SB+ as a transport or stand alone? I'm not sure now because of your
comment about needing digital inputs.

[SlimDevices: Audiophiles] SB vs SB+ vs Transporter as transports

2007-07-03 Thread darrenyeats

All,
Has anyone compared the following as TRANSPORTS:

SB vs SB+
SB vs Transporter
SB+ vs Transporter

If you believe that transports sound different, or if you believe they
don't, please don't respond about that. Sorry for the bluntness but
I've just spent 2 hours trawling through engineering arguments on an
old thread, and I'm bored of it!

So to be clear, has anyone *actually listened* to the above and
compared with their own ears? If so, please post your experiences!

Or, are there any shootout reports or other on-line reports on the
above?

Many thanks, Darren

OK, can you provide a few details?  How many trials did you do, and
what was your score?  Are you certain there were no clues you could use
to tell which was which?  For example when my SB3 powers on, there is a
slight pop from the speakers, so that would need to be avoided (for
example by turning down the volume during the power off/on cycle). 
Presumably the test wasn't double blind, but that's probably OK at this
level so long as your girlfriend was careful not to give you any clues,
verbal or otherwise.  

Mainly, the important thing is to go into the test in good faith,
understanding that what you thought you heard might be placebo, and
trying your best to eliminate all possible clues so as to make the test
fair.  If you do that, report a little bit on the details, and the
result is positive, people will take this seriously and try to
understand why it's happening.  Until then, the odds are overwhelming
that this is placebo - I say that based both on knowledge of jitter,
the SB3, etc., and on extensive experience with audiophiles.

Re: [SlimDevices: Audiophiles] external DAC could someone suggest anything?

2007-07-03 Thread Videodrome

With some of the lesser known products available from overseas, you have
lots of options to choose from. You may want to check out Pacific Valve
and Electric.  They offer a wide range of DACs that are real giant
killers and won't break the bank. Regarding the Benchmark DAC-1, I have
not heard one, so you can take the following comments as you see fit...

I seriously considered the Benchmark, and was convinced it was just a
question of when not if I would order one.  But as I did more homework
on the unit, I found 2 things that ruled it out for me: in nearly every
shootout I saw where the Benchmark was compared with other DACs, the
Benchmark always seemed to come out on the bottom.  Second, many folks
complained that, while revealing, the Benchmark was clinical sounding
and was not something they could live with long-term.  As I was looking
for something that approximated the sound of vinyl, that pretty much
ruled out the Benchmark for me. That said, I know the Benchmark has a
loyal following, so if it's your cup of tea, you can usually find them
on Audiogon for $200 - $300 under retail.

Lastly, zanash mentioned the Behringer SRC2496.  As he noted, it is
supposed to have pretty respectable DAC; but equally important, it
upsamples to 24 bit / 96kHz and provides jitter control, all for about
$129 online.   I have been researching this unit recently and will
probably add one to my system, using it upstream from my Musiland
MD-10. From what I've read, the jitter control and upsampling can make
even a budget-priced DAC compete with the big dogs like Lavry and
Benchmark.

[SlimDevices: Audiophiles] Analog attenuation

2007-07-03 Thread zork17

There is a lot of information about the necessity to match the source

Since everything is a bit technical for me (e.g.
http://wiki.slimdevices.com/index.cgi?ConnectToPowerAmp), can someone
please help me with this issue:
I have the Transporter as an only source and the amplifier is the XdA
from NHT (part of the Xd system).
It has an Input Sensitivity of 1.5V RMS
(http://nhthifi.com/2006/products/s/xda.html).
To get the best performance should I:
1) Use the attenuation inside the Transporter and use it's 'digital'
volume.
2) Buy a passive preamp.
3) Buy a regular preamp.

Here inte sweden we got 223V / 50 HZ i think in the us it´s 110V/60
Hz?

The hole chain must be perfect "from the power in the wall" to the
"speakers". 

We are talkin about very very fine detials here..

"isolation transformers" for the 230V / 50 HZ is quite expensive, not
all people have them.
And without them you gets a lot of dirt from the Power net..
It dosen´t matter how good your stereo is if you don´t have Clean
Power.


"isolation transformers" for the 230V / 50 HZ is one of the best
uppgrade i ever done!
This makes the hole stereo isolated from the power net.

My girfriend did a blindtest on me yesterday, yes it´s not in my mind..


"Hammer65" and i are goning to try with a Benchmark Dac or some Jitter
Measure device.

We think if we got some lines of code to the slimserver thats do the
same thing that happens during power off /On when you jumping between
tracks, our problem would be gone.

Fragmentation of the buffer in SB3 ? Jitter ? we realy don´t know.
But some thing happens when you jump between tracks...

If we start a hole album at power on the sound i good all the time. (if
we leave it on Track 1,2,3,4, etc)

Best Regards


/Mats :-)

Why have you not tried a blind test?  It would take you 5 minutes - far
less time than has been wasted so far discussing this.

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

2007-07-03 Thread zanash

Is the isolation tranformer internal or external 

I've built a unit that just plugs into the dig out and the dig ic
connects to it 

Oh by the way the effects i'm hearing are via a dac ! [either a src2496
or the dac section of the quad 99cdp2] So that discounts the ana output
stage in my case

thought the sb3 volume still operates..there for it must be working in
the digital domain ?

Perhaps you could offer the mods as a service?
