Hi Guys,
Thanks a lot for all your good advices! I think I'll stick to the SB3!

Good point. I was only able to get a bit-perfect stream from
foobar2000 because I was using an M-Audio Audiophile 2496 PCI card that
supported 44.1khz playback sample
Most of the built in sound on motherboards use an AC97 codec which is
fixed to 48KHz sample rate. Thus if you are playing 44.1 data its going
to be resampled by the software on the PC. So no it won't be bit
perfect.
I've measured the jitter (actually taken the spectrum on the clock) on
several m
Another issue is what the software player and PC sound apps & drivers
might be doing to the playback stream along the way. It's been a while
since I played with Softsqueeze, but when I tried it a few years ago I
was not getting bit-perfect playback (tested by playing a 5.1 DTS file

Not so... the optical digital outputs are directly driven by
electrical-to-optica
I presume that your mainboard and the SB alike have optical digital
outputs. So there should not be any electrical influence ones the
signal has passed the optoelectrical converter...
Anyway, I THINK it is all voodoo. A word which I come to like since I
got myself into the very expensive hobby of
No, its not always the same. Although the sequence of 1s and 0s ought
to be the same, this has to be represented by an analog electrical or
optical signal which can have timing or other imperfections. These
imperfections may or may not trouble the device that is receiving the
signal: a signal wi
Thanks Ceejay,
So the electrical noise of the computer may disturb the s/pdf signal
sent to the DAC. But, is it true that a s/pdf signal itself is always
"the same", independant of the source(I'm not technically educated as
you might have guessed)?
Thanks, Anko

Well, there is a reason why there *might* be a difference - the
electrical noise within a computer case is generally very high, and
could easily do nasty things to the level of jitter on the digital
output.
Whether thats important in your case will depend on the ability of the
Arcam's DAC to reje
Hi,
I've got a SB3 and I'm very satisfied. But, I just replaced my whole
stereo to the room where my computer is. And I bought a new motherboard
(Asus P5B) with onboard audio and a s/pdf output.
So far, I connected the SB3 via toslink to an Arcam DAC. Now I can also
connect the Arcam directly
