Yea, i found that room is very important, BUT ... Bass management with Marantz felt like it was not even close to what Yamaha 2020 or Denon 4311 did. I am still looking to get back the musicality and sound detail that Yamaha gave me during movies. It was just so much more exciting. But ... one can argue that the detail that I heard was due to Yamaha being so high toned and so in a way it overemphasizes the high tones that should not even sound that way, who knows.
Like I said, I am hoping that Yamah RX-V3900 that I got for just $600 does better than Denon 4311 or at least close so that I won't feel the need to pay twice as much to keep Denon.,
