So Maluvia says:
I built some
D/As out of a Crystal 24-bit evaluation board that blew the
socks off an equivalent Apogee -- with a good clean power supply and
clock. For about $200 US!
Wow - that's really encouraging!
(BTW, where does one come by something like a Crystal evaluation board?)
If you can convince a Crystal Semiconductor wholesaler that they should
sell an engineering eval. unit to you, then that's where. I don't know
who the industrial distributors might be for your region, though. You can
try this for other companies as well.

Caveat: yes -- that did include a careful and good word-clock. I agree
with all comments about jitter _at the convertor_ I've seen so far; but
most decent convertors won't mangle an external clock, and you can add a
spendy stable clock later if you like -- just add next year's tax-refund
as well!
