Hard Disc Player Sound Quality
 
PC based hard disc players seem to be a common topic of discussion in
this ng at the moment
Has anyone any comments on likely sound quality compared to a
standalone CD player?
I'm thinking along the lines of feeding digital audio from a PC
soundcard via optical link to a standalone Musical Fidelity DAC, then
to amp and speakers.
The CDs would be stored on the hard disc as wav files or flac
(lossless compression)
My current CD player is a Marantz CD6000OSE

I have one! Good innit?


Sure is - that's why I'm a bit worried about possibly ending up with
inferior sound quality, for the sake of convenience.

Most likely you will be playing pack at 48kHz then, so *better* than CD
quality, all other things allowing...

Where would he be getting this 48KHz stuff from? :-)

To answer the question - yes, a computer will squirt bits into your
DAC just as well as any other digital source.

In theory.

In practice (despite the recent threads) I very much doubt that any sort
of half-decent upsampling is audible at all.

All other things being equal, the sound quality should be the same when they
are both playing the same data. The PC-based player could have an edge
because the data it delivers to your DAC might have fewer uncorrected
errors. This happens because playing a CD on a regular CD player is a
one-pass process with no opportunity for retries. The better CD ripping
programs will retry erroneous data reads, which can significantly improve
the quality of the actual data delivered to your DAC.

The sound quality of this system would be limited by the DAC.

The CDs would be stored on the hard disc as wav files or flac
(lossless compression)


Been there, done that, it works.

You just need a good sound card that doesn't resample or otherwise butcher
the digital signal. You need to be sure to avoid contaminating the digital
signal with a ground loop. But you said "optical link" didn't you? That
pretty well eliminates ground loops as a source of problems!

Yes, it's going to be an Audigy 2 NX, external (USB 2.0), because the
PC I'm planning to use only takes low profile PCI cards, and a decent
sound card in this form factor seems to be scarce as hobby-horses'
doo-doos

I did like that suggstion in another thread about PC based players,
where the poster had gone for a monitor-less system and controlled it
using VNC from a laptop! After all, a just decent s/h laptop is
probably cheaper than a new TFT monitor.

If you're only after digital out, who needs a decent card? anything will do.

In analog lines they can cause audible hum, in digital lines they can cause
lots of jitter.

No, it's different - The 66 has more channels of I/O, a break-out box
and it supports +4dBu signal levels. I haven't used one, so can't
comment on the analogue signal quality.

I use the Audiophile 24/96 a lot and like it (not the best in absolute
quality terms for the money, but plenty good enough) and we have a Delta
1010 at work, which is very good.

Agreed.

However, any number of poorly-designed systems have hit the marketplace.

We then have reports that a given (incompetently designed) DAC is so
*revealing* that it allows you to clearly hear differences between
transports and digital interconnect cables... Of course you are supposed to
run right out and buy one!

Unfortunately, these are thin on the ground in high-end audio........

Heck, some of those clowns don't even put in the reconstruction
filter! No, really, check out AudioNote.....................

BTW, a PLL *reduces* the jitter problem, only a synchronous master
clock can *eliminate* jitter.

Agreed.

However, any number of poorly-designed systems have hit the marketplace.

We then have reports that a given (incompetently designed) DAC is so
*revealing* that it allows you to clearly hear differences between
transports and digital interconnect cables... Of course you are supposed to
run right out and buy one!


**** man, I'll just bin my Arcam DBB3 right now ;-)


Well, that'd be a start - then you could buy a top-class one-box
player, such as an Arcam 9 or 23. Problem solved.

Unfortunately, these are thin on the ground in high-end audio........

Heck, some of those clowns don't even put in the reconstruction
filter! No, really, check out AudioNote.....................


LOL ;-)

BTW, a PLL *reduces* the jitter problem, only a synchronous master
clock can *eliminate* jitter.


nah. as long as we're talking about jitter and not gross long-timebase
clock frequency drifts, a good PLL will eliminate it.

What exactly is not 'top class' about the DBB3 ?

What about sample rate conversion?

pointless, as without MASSIVE buffers its not possible to do without errors or aliasing.

better to use a PLL as any quartz clock will give adequate frequency stability within the few-kilohertz range used in audio. with a PLL jitter is irrelevant (with a good design) and you end up with the DAC locked to an adequately stable clock anyway, without the issues involved in reclocking.

There are uses for reclocking system (ie. mixing and production uses) but playback isnt one of them.
