[QUOTE="gbyleveldt, post: 19902, member: 122"] Hi Devil, a) It is possible, just have to test it on some gear that'll output that format. There are some fundamental differences in the protocol of AES and SPDif and you would want something that'll elegantly handle both formats without wipping open the DAC to change jumpers. Electrically it's already provided for on the DAC. b) Yes, also possible, but with caps feeding the ouputs. After the chat with croak about this, I'm wondering if it won't be better using balanced transformers to do this. Pricey, but definately worth it as the PCM chip can drive a fat amount of current (relatively speaking). As I alluded to earlier, I'd rather do up a new design for proper balanced operation, to be honest. This'll use two PCM1794 Dacs. This'll be more elegant and wouldn't need the same compromises to be made. [/QUOTE]
