I have the Seventy Nine Dollar Converter wired up with multiple sources like the soundcard out, the DAT, the CD player. That feeds the 2 track return of the console for monitoring. I have better stuff here for tracking/mixing like BB PCM1704, 1792, etc, but this is convienient as I just pop the switch and listen though the console or headphones. I like this DAC better than the top-o-line Crystal CS4398, their top-o-line part. The imaging is good on this BB part.
The PCM4222EVM needs a power supply, that's it. Everything else is mounted, balanced XLR/TRS inputs, dual s/pdif and AES outputs. Add + and - 15 volts and + 5 volts and it's ready to go. A better value will not be found.
