I've got studio 60's, studio center, and studio adp's V.2's running on a marantz and for the life of me can't hear the brightness that I keep Hearing in alot of post's. this may be credited to the marantz amp though, it has a laid back warm sound compared to yamaha's and denons that I've heard...
I have the pw 1200 and its plenty loud. got it for $650 canadian. I would recommend checking it out if you can. sorry must have hit the post button twice.
