What's the better, High Powered SS Amp?


Anyone have experience comparing high powered solid state amps?
What's best in driving inefficient speaker's such as mbl's etc...

McIntosh 1201's
Simaudio Moon Rocks
Pass Labs X600 or X1000's
Classe Omega's
Any other's?......

other than mbl amps.

What's most important to me is dynamics, resolution and lack of grain especially at the treble region. I listen to jazz, vocals, acoustic music most of the time.

Hi,
I've had Rowland 9Ti's, Pass 600's (sold them to Muralman), Krell 750 Mcx's and now am totally delighted with my Boulder 2060. They can effortlessly drive anything, and now that I've paired it with the new ARC Ref3 preamp, I am in heaven. If you want more details on how the previous amps performed in my system, i would be glad to oblige. BTW, they're driving Dynaudio Temptations, which really love the power.

David, I am sure the Boulder amp is a great solid state amp. For something totally knew, try the H2O Signature monos. I know I will never go back to SS.
Which speaker did you try, how big is your room, and how loud do you usually listen? I have used a Bryston 3B-ST with Proac Response 1.5s, Magnepan MG-12QRs, and Dynaudio Contour 3.0s in a 13' x 16' room. I don't really crank it as my downstairs neighbors reported me for shaking a picture off their wall.

While I would not consider Bryston amps powerhouses for driving 1 ohm loads, they are certainly adequate with a lot of typical speakers.
Deshapiro,...how did the X-600's stack up against the Krell 750 monoblocks in your system?

What made you forgo the Krell monoblocks for the Boulder stereo amp? What are the improvements of the Boulder over the Krells?
At the time that I had those amps, I had Avalon Osiris speakers, which were a very difficult load to drive. The Pass' had excellent low-level detail, what I would call a "clean" sound. But, they were also lacking in the midrange with a thin, not very sweet tone. The Krells had much more tonality and richness and were much more musical,but didn't image or soundstage as well. The Boulder does it all: imaging, resolution, detail, rich musical sound. I have since changed speakers o the Dynaudios and there is great synergy . They love the power.
