This is a bit unusual. I decided to upgrade my RX-A810 to an RX-A2030. I chose the RX-A2030 because 1. Yamaha, 2. It has pre-inputs so it should never be obsolete.\n\nWhat I didn’t expect? I prefer the sound of my RX-A810. The RX-A2030 sounds.... harsh. My suspicion is the RX-A2030 has a more precise\/better DAC, and thus any errors in calibration are compounded. Either way, with the RX-A810 I got what I felt was like “transparent” sound. That is to say, you can’t distinguish the speakers. I tried multiple calibrations and different settings on the RX-A2030, but it’s the same, even in 2-channel stereo running through my M-65 amplifier (this clues me in to the DAC).
