I just removed a MacMini M1 and replaced it with a Nucleus as a test to see if the hype is real. I am here to tell you, IT IS REAL. The nucleus was literally like I lifted a curtain..And I have a gigafoil working "isolate" the system from the Server. So there goes your theory. It's real, embrace it Servers are as important (maybe more) important than DACs. If you haven't listened to a dedicated Server it's nothing more than an opinion. If you're happy with the sound you have, great. But know for a fact a dedicated matters and will improve the sound.
I returned the Nucleus and went straight for the top of the line Antipodes.
