What I did when I needed an ADC, is to get a Crystal Semiconductors
evaluation board. They do them also for their DAC chips. This is a
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
