I'd hope it's a lot quieter than that :-)

Is that card another name for the Audiophile 24/96?....

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.

What's the prob with ground loops ?

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

I'll not ask what jitter is, but I guess it can't be good

its 'noise' in the tioming of the digital pulses, ie. they arrive slightly earlier or later than they should.

jitter should be *irrelevant* on any well designed system. Even quite large amounts of it.

Please see:

http://www.pcavtech.com/soundcards/delta-66/index.htm

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

http://www.pcavtech.com/play-rec/cd67se/index.htm

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

I guess the site's down.

Nope. Perhaps your ISP is not doing his job.

jitter should be *irrelevant* on any well designed system. Even quite large amounts of it.

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.

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!
