complete ADC or DAC on a board, with DIP switches for setting it up.
All you need is a power supply and a box to put it into. They cost
about
the same as the DAC-AH, but you get the latest chipset.

How do you get such a thing? Knock twice and ask for Crystal?

In your case, what was your receiver chip and what was the DAC chip?
How long ago? Did it sound good? Do tell us more. Andy

The best thing to do is to look up www.crystal.com Find the chip you
want and see if they do an evaluation board. You can download the manual
for the chip and the board, and make sure it's exactly what you need.

Then, find a Crystal Semiconductors distributor in your territory, get a
price and buy one. I bought the CS5335 ADC board about 7 years ago when
I got my Meridian D1500 'speakers as these only have digital inputs, so
I have to convert my analogue sources. The CS5335 is a 20 bit ADC, and I
leave it on 48k sampling, which is fine for my vinyl and FM radio.

As to sound, I compared it with one commercial unit, the Lindos LSC24
A-D/D-A converter and couldn't hear any difference with the sources
available. I also put it back-to-back ( Digital out from CD to LSC24,
analogue out of the LSC24 to Crystal ADC, digital out to 'speakers) with
the LSC24 and sent a digital signal to my 'speakers and again, it was
transparent using a CD as a source. This, to me, means that I wouldn't
be deriving any benefit from something "better".
