OK, I'll have another crack at this.
While my Onix has digital outs I would not be adverse to using a PC to send to a DAC if that is an option.. but I dont want to waste my time and money.
I don't quite understand. How would you use a "PC"?
If you connect a high quality DAC to the digital outs, you may get better sound. Or you may not. The Onix has Burr-Brown 1732 24-bit/96kHz DACs and HDCD decoding, so it's probably doing a pretty fair job for a $300 player. It's weakness is probably the output stage.
I am sorry of this was covered.. I just spent 3 hours scouring forums and while there is tons of DAC info I did not find a thread that addressed this directly.
Sorry, what exactly is "this"?
I'm a little confused as to what you are asking. Are you thinking of switching over to computer-based digital playback?
