I have MFA 200C monoblocks which are rated at 200 watts per side into 8 ohms and they switch to triode mode for less output. They use 6 KT90s a side. I've had them for about 8 years and have really enjoyed them. Then again, I used them primarily with Snell Type A/IIs which are very smooth. The tube amps probably made things even smoother than they needed to be. I have had little trouble with them. I had to resolder connections to the switch on one side and to the fuse on the other side; and I had to have a part replaced on both. John Nunez who used to work on these amps with MFA replaced the part and indicated that it was a problem with that part but that otherwise they ususally don't have problems, and I can vouch for that, other than the aforementioned. They run very hot and don't have fans. Seem to have good reserves of power, good dynamic contrast, bass isn't the tightest I've heard but its there. All hand wired. Bob Bergner I think at RB Audio sells the new Bruce Moore amps and provides support, maintenance etc, as I understand it.
The new Bruce Moore amps seem bullet proof compared to the MFAs, which are more a clssic look, cosmetically. A lot of heavy metal on those new ones.
Since Iv'e changed to Revels, I can't say yet how they synergize. See the thread under amps/preamps entitled "Opinions on why this system is uninvolving", for further discusssion re that system.
