HTR-5890 good
I have been using the HTR-5890 for 4 months now. I am yet to find fault with this receiver.
Once you get you receiver, try this test. put in someting with audio (cd or dvd) and pause it. Now turn the volume all the way up. Hear anything? With the HTR-5890, I hear dead silence. That is the sign of a good amp inside.
Regarding power, never felt the lack of it, in fact, I had to move to a bigger apartment so that I could open out my setup
, the speakers seem to work optimally only if a minimum SPL is output by them. But that has nothing to do with the amp.
Hope this helps in your decision.
