Summary: I was so disappointed by this amp. My Onkyo M-282 appears much better than the M-5000R. The M-5000R seemed not to have enough power. 80 watts is the maximum before the sounds weakens in my opinion. The Onkyo M-282 is an incredible value and sound performance, warm, dynamic, musical, bass punchy and crisp. I was mislead by the reviews and weight of M-5000R.
