As others have penned it’s X1 for Roon. Full disclosure I bought a used X1 and I’am bery happy.
I have listened to both but not in the same room and it’s the room (the while shebang) that matters most.
Aurender A20 or Lumin X1
I considering one of these as my next DAC/streamer. From a purely technical perspective, which one should I buy?
