Amp for some new Gallos

I am aware of the break-in period. For more than two weeks I have left them cranked when I left for work...the neighbors love me. I have been using a Rotel amp (200 wpc), for the break-in but I want to experiment with something different and a little further up the quality chain. I am getting conflicting info with respect to the power requirements. Some say they can be driven with SETs, others say they like power. I would like to know what amp could remove the grainy quality that I get with the Rotel playing the Kronos Quartet. The C-J MV60 looks appealing.

Why not the same amp that Anthony Gallo uses himself - Spectron Audio Musician III Signature. Many other speaker designers also use this amp (Albert Von Schweiker, late John Danlavy etc).
These speakers are really love high current!!!

Thanks Rafael. I've heard that pairing Class D amps (which is what I believe the Spectron Audio Musician III is) can cause problems with tube pre-amps. I don't understand the reason. But until I know what to look out for, I will avoiding the whole class D thing. Also, I live in a smallish apt and 600 W would put me in the street.

I'm driving my ref 3s with a bel canto evo 6 and I like the match very much. Even at low sound levels, the combo is detailed and quite musical. By brother who is impossible to impress praised the sound of my system on his recent visit. I'm in the camp of you can't have too much power. I'm even suspicious of the "tubes rule" dogma band wagon thats in vogue these days.

I once talked to the manager/owner of maple shades. They love Gallo. I havent heard them myself..but they mentioned that they make an amp and integrated tube amp thats very very good with these speakers. I would give them a call. I think they have a pretty good reputation of what good sound is.
