Dear dr,
I have denon 3802, m-80's, vp 150, qs8, sunfire sub and I am truly delighted with the result. I now listen to 85% music and although I have qs8 surrounds, I now prefer stereo listening over dolbyII or neo-6 because they sound so pure. I keep being amazed by dynamics, clarity and precision. I also find that I do not need to crank up the volume anymore to totally enjoy full dynamic and immersion of music. Those speakers are really not hard to drive. I listen at -20 and at -10 it is almost too loud (if such a thing exists!!). Denon 4800 will be GREAT with m-80's.
