Crystal Semiconductor in Austin, (512) 445 7222, manufactures several
very interesting A/D converters, in case anyone is interested.  One is a
two-channel 16-bit Delta Sigma converter designed specifically for
digital audio.  Very nice parts, and I believe they go for around $100
quantity one.  The "sample and holds," anti-aliasing and decimation
filtersand voltage reference are all built in (28-pin package).
