:) I've a M Audio Delta 66 sound card and wonder what you experts think

:)Compare that to a similar report for a good CD player:

A DNS lookup error occurred because the request timed out during the
lookup.

I guess the site's down.




Looking at your time of posting I would say you caught them at a bad time
too - feeding the gerbils?

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 ;-)

hehehe

jitter should be *irrelevant* on any well designed system. Even quite

At the point of conversion, it's absolutely critical. That's the main
problem with standalone DACs for CD.


The point being, of course, that any *WELL* designed system will use a
good PLL and thus eliminate the problem.


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.

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.

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.
