MQA or no MQA, apple's USB implementation is the best across all hardware segments in God's green earth. Now dont ask me if i double blind a/b d it. I can say its the case like i can say Speyside single malt gives a better high than Johnny red , black . you would definitely need Green/gold blue for a comparable high, but its different too. I installed ropieee on raspberry pi, and ran it as roon bridge, and i connected my iphone/ipad/mac with roon remote over usb to my trusty E50, ropieee on raspberry pi pretty much sucks, in compariosn to usb feed from apple hardware, also once wiim is roon ready in general release mode, maybe ill get good output, but not getting my hopes up. You got to pay for the good stuff boys/ gentlemen
