I've been looking inside one of these at what

reconcile is why the DCX is so (comparatively) noisy
given the specs of the chips. There are a couple of
possibilites that I can see:
a) It uses a switching PSU for some reason instead of
a linear
b) The signals after the DACs but before the opamp o/p
are carried on an unshielded ribbon cable

Any other ideas?
Am I being unreasonable?

**Yep. I've used the 2496 in several installations. It
is very, very impressive. It's S/N performance is
excellent.


But nowhere near as impressive as the XTA at around
$3500. Why?

Possibly down to both a different DSP processor and the
EQ algorithms used. You can get serious internal clipping
problems in digital equalisers esp at low frequencies
IIRC and that results in you having to discard what might
otherwise seem to be adequate headroom to compensate and
that then brings up the noise floor.

What's the DSP chip in the DCX2496 ? If it's that TI TMS
something (TMS57002 ?) , that'll be the problem.

It's an Analog Devices SHARC chip.

The converters are AKM parts.
