Very good home theater amp, bought to replace an old RX v800- Yamaha that still works!!!! I hope this one will do just as well. In terms of build quality as well as sound quality, for now it’s perfect.
A very small downside with the MusicCast app, which from time to time doesn’t connect to my Qobuz account. I restart it and everything works. If I had known, I would have bought it sooner!!
