Music Reference RM9 - user comments please


I am considering of getting a used RM9 for my Merlin-TSM, can any user of the amp comments.
vintage
Owned one a few years ago - a classic tube amp that is reliable and easy to live with.
I have compared it to nad it is far better,I have compared it to harmon kardon monoblocs,goldentube se 100,it is far better.The only amp that I heard that beat it was atmasphere ma-2 which cost 4 times the price.
That what I am wondering; how does the RM9 compare Atmasphere, CAT, ARC Ref Series, etc.? I willing to believe they are every bot as good (I don't care about the price difference which I think is relevant at this level). I'm listening to the RM10 MK II - the little 35 watter - and it does not give up much to higher priced stuff. Next week I'm bringing the RM10 over to compare with a fella that has the RM9Special - should be interesting as we both own the same speakers.
Back in the '80s I evaluated and bought a RM-9 to replace my restored Marantz 8B. It drove my Vandersteen 2 (whatever was latest version at the time). Beautiful sounding and looking, I might still own it except I bought larger speakers for which 100 wpc was not sufficient.

Looking back, it was one of the finest pieces of gear I've owned in over 40 years in this hobby.
I'll say one thing, I've never heard a bad word said about a MR amp by anyone who has owned one.
