Looking for power amp with warm, smooth sound


Have some Monitor Audio RS6's that are sounding bright and fatigueing to my ears with my Marantz 6003 receiver. Would adding a power amp with warmth tone down the brightness and add more fullness to the sound of the speakers? I would use the Marantz as a pre for now. Any recommendations for one under about $1200?

By definition power amp is NOT suppose to affect the sound.
The only job power amp is doing is amplifying signal. If you find power amp with warm sound or sharp sound or smooth sound it can only mean one thing : the amp is broken.
It could be that it was damaged in shipping or damaged by starry-eyed, kitchen table engineer.
In either case my advise would be to avoid such product or be eventually dissapointed.
Lefty - OK. Nevermind then. I had some suggestions of dealers to visit if you were in southeast. You might want to check out Audiokinesis or Adaleus, both out west, though not in Seattle. Their speakers and amp suggestions are far from bright.
