I do not use onboard computer DACs. Never found one that I liked.
Yes I am insanely fussy about sound quality compared to most folks.
It used to be that I would get a sound card in order to get digital sound out. SPDIF so I could run it through a nice external DAC (typical good ones cost about $1K and up.).
Nowadays that isn't needed any more. Integrated sound almost always comes with SPDIF out, and most external DACs have USB capability. So I don't need sound cards to get the sound into my DAC these days.
