Amp for Compact 7ES3, to replace gainclone

Hi everyone...
I currently am using a gainclone amp based on the LM3886 to power my Harbeth Compact 7, and am thinking to replace them. I recently completed a twisted pear DAC as well as a pass b1 buffer pre...
I have tried a few amps with these speakers, including vintage luxman integrated (wooly and soft), McIntosh MC275 (flabby bass but real nice mid/highs), a Densen B110 (nice PRAT but not a great soundstage and overall not a good choice for classical/jazz) as well as a Pass INT150 (very very good)
Overall, I like the Pass most I suppose, but I found that it wasn't a great enough improvement to warrant the huge increase in price over my $100 chipamp.
I am pretty convinced I need something with some juice, but also with a high damping factor to control those woofers...
Anyone have any good power amp suggestions for me?
Regards,
Byron
