available on a file server?
I certainly don't. That's why I use silent/fanless Sun Ray thin clients
for a similar application. They can be had for under 50 bucks with
careful shopping.

And you realise that the signal *originated* in the analogue domain ? Digital *can't* make
the original better - lmao !
Analogue has no trouble going way, way beyond 91dB s/n ( A weighted ). In such a trivial
application the analogue noise should be around - 110dB ( unweighted ) - that's around
-120dB typically A weighted.
To suggest that any analogue circuit is responsible for the poor noise figure is plain
idiotic and shows a basic failure to understand the technology.
I see you can't refute the THD issue. Analogue can easily do 0.001% THD ( and better ) - i.e
over ten times better than the Turtle Beach spec *unweighted* ! Possibly 100 times better
unweighted but I've never previously seen a manufacturer so desperate as to quote THD with a
weighting. It just isn't done ! It's a wholly inappropriate thing to use weighting for.

FM's rather noisy Mark. Distortion and channel separation aren't exactly
great either. Certainly a *big* reduction in quality compared to CD.

Besides who wants to so nerdy as to run a file server just to listen to music
? You won't get laid that way !

The noise figures are for the analog outputs.

I think you're missing the point. I know it actually.
The analogue output noise will be determined by the ADC outouts - and hence
the 'system performance' - *not* the other way round ! I design this kind of
stuff you know ! I know my shit. Any *half competent* analogue line level
output will be capable of 110dB s/n or better
OTOH if you wish to wallow in your ignorance - please be my guest.

Sure, but the point is they do not aply to the digital output. You were
saying that the noise figures showed the box was not handing .wav files.
That's wrong; the noise figures show the performance of the D-to-A part of
the product, and are nothing to do with whether it is handling .wav files.

And you're now talkng gobbledegook.
I don't actually care matey.
I *know* the performance that linear 16 bit pcm can supply and the specs I
quoted from the website were *clearly * not representative of same.
In short, I know you're talking nonsense.
If you think you're smarter than me then please feel free to fool yourself.

Hey Pooh Bear,
I have a suspicion that very little, if any, of the stereo equipment one might
find in, say, Wal*Mart meets this spec! Would you agree?

Wal Mart is indeed another story.
I tend to talk mainly of what has become to be known as 'pro-sumer' gear. Stuff
that would once have clearly been seen to have 'pro' specs but is now available at
a 'consumer' price.
I have zero interest in the shit sold by Wal Mart and their ilk. Even if it does
have a supposed *big name* on it.

Beg to differ. Ever tried a numerically controlled exciter such as a
Harris DIGIT CD modulator?.

Very impressive, but...
(1) A great FM exciter does not guarantee a clean signal as
received. There's many a slip between the cup and the lip.
(2) As big and expensive as this Harris puppy is, it can
only do 78 dB dynamic range. That can be matched or beaten
by a $70 PC sound card. I'm talking stereo performance
compared to stereo performance.
Again, add antennas, signal path, and even an exceptionally
good FM receiver, and real-world performance through the
whole loop is not all that wonderful by modern standards.
Admittedly the basic performance specs of 78 dB dynamic
range and 0.5 dB FR aren't shabby, but it doesn't compare to
what you can do with digital coding for a tiny fraction of
the price.
(3) The worst thing about FM broadcasting is what they do to
the signal intentionally, not accidentally. Of course we
can't blame the medium for that.

Well the jukebox, actually 3 x 100CD auto-changer units tucked away in
a hall cabinet, is operated by a remote from the comfort of my couch
in the great room ;-)

That's what I thought you'd say. OK, I know where you're coming from now... I
just hope you realize that, by volume, there's a lot more "shit sold by
Wal*Mart" than pro-sumer stuff! (Tried to buy an SVHS VCR lately?)
I had a debate years ago with a fellow college student about the best way to
make money selling electronics... he wanted the Wal*Mart approach (low cost,
high volume, "good enough") whereas I advocated the "boutiquey" approach
(lower volumes, noticeable higher cost, honest-to-God specs that would meet
with the approval of even the most discerning Pooh Bears). I still prefer the
later, but I can see now how, from many angles, my friend's approach is a lot
easier to implement for the average Joe, even if there is a lot more
competition.
