Looking for a module that can take an AES/EBU signal (24/96 or better)
and give me a low noise analog out (105dB s/n). At a not ludicrous
price. For inclusion in a powered speaker. Any ideas?

105 dB sn is a hard act to follow. I'm not sure anything out there really
exists if you really want that number to apply across the 20 KHz passband.
if you want it to apply all the way up to 48 Khz, I think you're a good order
of magnitude off.

It's not hard to build your own DAC with a Yamaha receiver chip and a
Cirrus DAC chip and a discrete I/V stage... but it's really really hard to
get better than 100 dB SNR.... and 105 dB is a whole lot better than 100 dB...

!!! Wow!
That looks impressive.

I'll get one.
Quick Q, since I haven't bothered to look yet - any problems with taking
the output and feeding it through a low power passive xover before the
power amp (instead of after)?

-116 dB, "A"-weighted

IMHO not sooo impressive:

That's actually pretty good, all things considered. I bet a nickel that
it doesn't actually meet that spec, though. Give it a try and see.

If you're looking for a standalone box instead of a module intended for
incorporation into production designs, check out the now-discontinued
Entech 203.2 DAC. Actual noise is something in the ballpark of -94 dBFS
unweighted, which is pretty impressive for something so cheap, and the
distortion numbers are quite respectable. Another nice thing is that
if you look at the noise floor, it is fairly flat rather than having
noticeable spikes here and there. They turn up used at good prices and
they actually sound remarkable for a cheapie.

Any idea who makes it?
I would like to buy one from a UK supplier if possible.

I have no idea, because I don't know what the DAC's output buffers are like.

No need to use a line level passive crossover, as you can probably steal
enough power from the DAC to run a couple of more op amps for an active
crossover.

Citizens of the PRC.

Rotsa ruck! ;-)

Jim Williams has touted the following, which goes in and out of sale at
MCM:

Here's a nice low budget DAC;

MCM Electronics P/N # 50-7774

www.mcmelectronics.com

It's a 24 bit 96k dac with 2 coax and 2 toslink inputs, a fixed and
variable output and a headphone amp. It uses a nice BurrBrown PCM1716
dac chip with a crystal CS8414 input reciever chip. The caps are all 105
degree rated. The weak spot is the 4558 opamp, I replaced it with a
National LME49722MA, a very nice improvement.
