I would look into DACs which are noted as being source agnostic or into splitting your budget for components such as the Regen making the rounds which filter the line between PC & DAC.
Personally haven’t tried the above however I have compared an Ultrabook as source compared to a tweaked performance tower and found the portable machine highly restrictive to the performance of my DAC. Were it more than an expirament I’d have immediately traded in my DAC!
In an attempt to level the playing field I added the same OS tweaks/playback software to the ultrabook; unlike the full sized machine the sound remained consistent through all the tweaks I made.
