What Is Best Monoblocks For Around $10,000 Used?

I'm searching for an amplifier upgrade in my system. My system is presently made up of a Classe CA-401 amp, Krell HTS 7.1 pre-pro, Piega P10 loudspeakers and Mark Levinson No.39 CD player. (The P10's and ML 39 will eventually be upgraded.) I listen to 2-channel redbook CD's, but the system also does Home Theater with a Krell Theater Amp Standard handling the center channel, rear channel and Zone 2.

I'm searching for a pair of mono-blocks that sells in the used market for about $10,000 (plus or minus), to replace the Classe CA-401 stereo amp. I've considered the Krell 450Mcx, but heard it sounds dark. (I don't know what dark is.) I've considered the Musical Fidelity KW amps, but they only have single ended inputs. The Pass Labs X600 may not give me the bass I'd like to have.

Can anyone make any suggestions on a good, resolving pair of mono-blocks?

Thank you.

Have you listened to the Krell Theater amp on the front channels? It may give you more of an idea what the bigger Krells may sound like.

I second the Lamms. I don't think they can be beat in this price range. You don't mention power restrictions, though the amps you've mentioned do have more power than the Lamms, but lack the Lamm's sonic refinement. If you can get by with a mere 200 wpc, check out a pair of Lamm 2.2's.

Dark sound usually suggests that the highs are slightly rolled off.

You need to hear the Pass Labs X600 mono blocks. The bass is exceptional and the amps pull in detail in the entire range. You can find them used for around $7500. I have absolutely no desire to trade, upgrade or sell mine. They're that good!

I didn't specify a power requirement, since as I mentioned, I will eventually be upgrading the speakers. If I can find a pair of outstanding amps in the lower power range (>200wpc), then I must search out more efficient speakers (Wilson, etc). That is why I'm seeking an amp upgrade first. Either way, the amp should have enough "beef" to satisfy the needs of my large 8000 cubic foot room.
