I got back my M90 amp from after purchase cleaning/inspection/bench test, and
there were just a couple issues. Power meter LED replacement (4 of Them) and
modern cap update, was my call. The guy I use is over 60yrs old and has seen
hundreds of amps, and rated this right up there. It's very musical, lots of punch,
and well designed. It's like a dual mono set-up, but in the same chassis. It was
bench tested in my presence with his normal test set-up, a pioneer spec1 pre, run
thru JBL 4312a's with 10g wire, and it just cooked in that rig. If anyones working
on a vintage rig, I strongly advise looking at this amp, or it's updated brother the
M91. The rotel I used will be "demoted" to surround/back channel duty for movie
playback. For music it will be this amp. It's very clear, thats what it was built for.
