Guys, my main rig is PC based.
I use an optical or SP/DIF out from my motherboard (Asus Z77 Sabertooth). DACs are my Audio GD Ref. 5 or DAC19DSP (both are pretty well regarded DAC's). Finally I output RCA to my Micro Tube and in future will be outputting ACSS to an NFB-6 (about to order).
My query is:
1) Is my onboard audio solutions coaxial/optical out good enough, or do I need a soundcard?
2) Do I need a good optical cable/coaxial cable? I am using default ones by Audio GD.
