I believe my 568.2 had Crystal DACs so my *guess* would be Crystal. Also keep in mind that circuits around the DACs (as well as processing) are just as important as the DAC itself. The OA13 DAC card is a killer.

Keep in mind that 861 has several DAC boards.

See the Price List over on the wiki for the different DAC boards. There are also older ones not listed.

If you think listening to music is fun, try learning an instrument.
