Before I settled for A-9070, I tried also the A9000R.Pareho lang sila except meron usb input na di ko kelangan kasi gumagamit din ako ng separate DAC. Pwede pa din naman magamit ang built-in DAC thru optical & coaxial inputs.
As for the speakers pairing, ok naman sa polk rti A3, Epos M 12i & my DiYs Audio Nirvana & MarkAudio...
