Wadia has been calling their DACs "Computers" since 1988 when they released their 2000 Decoding Computer putting them well ahead of our curve. The new 121Decoding Computer ($1,499) is a DAC/digital preamp that offers Asynchronous USB, AES/EBU (XLR), Coax (RCA & BNC), Toslink, and up to 24-bit/192kHz on all of those inputs. There are pairs of balanced XLR and unbalanced RCA outputs as well as a headphone output stage and aluminum IR remote. Wadia includes their Windows drivers on a thumb drive which is a nice touch (they're also available via download from the Wadia website).
