Thats what I think also, I have a i7 6700K, 32 gig ram and 5 SSD’s and many HDD’s, the motherboard has some shielding going all around the mobo, onboard audio is disabled and I use a xonar sound card for optical out, but usually use chords usb driver.
Spread spectrum is enabled in the bios and the motherboard is fitted with solid caps. My psu is corsair ax1600i which has a crazy stable output, and I would bet anyone to do a blind test with a server against my pc to see if there was any audible differences. Even golden ears wouldn’t hear a difference.
Saying that, I still want a server as my pc’s are too noisy and I can’t have it/them turned on 24/7, which I could do with a quiet server. That was one of the reasons I bought a chrome cast audio, so I could listen to hms and tt2 without my pc being on, but, the CCA is dodgy, as it can’t play 96khz files without blowing up.
I’ve locked it to 44.1, 48 and 88.2khz via roon and it works, but I want it to also play 96khz, but google are taking their sweet ass time to fix it.
A good motherboard will be just as good hardware wise, when compared to an expensive server.
