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.

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.
I've hear nice things about the Lamm 2.2 amp. What types of speakers would be suitable for this amp?

Worldcat - You are correct. CITADEL's are hard to find. However, with their modest power rating of 425>8 and 650>4 ohms, they don't seem to have the beef of amps with larger power supplies when used with speakers of lower impedance. My Classe CA-401's runs 400>8 and 800>4 ohms; and, I sometimes run out of steam when driving my Piega P10's rated at 4 ohms. I have not listened to the Citadel's, but heard nice things about them. Can you be more specific what it is about their sound that is alluring? Thanks
Can anyone comment on the Krell 450 Mcx monoblocks? Positive, or otherwise? Would love to hear some feedback on these highly regarded amps.

re: Krell 450 Mcx
By 'highly regarded' I should have explained better. That is not from reviews, but from general reaction. Many place these on a higher standard. If they are not exceptional amps, perhaps that may be why there are not many reviews on them? If they are exceptional amps, I'd love to hear that, too.
