The right amp to biamp with McIntosh MC275 Mk V?


After a bit of searching,and a look in the manual,i have not been able to find the "gain" for the McIntosh MC 275 mk V. I am running this in the balanced mode.
I want to run this amp on the tweeter and the mid on the top terminals of a pair of Von Schweikert VR-7's. This is the older "one box" design speaker rated at 91db.
For the dual woofers i want to find a great matching amp for what i believe is "vertical biamping" -without a crossover.
A solid state,or class "D" amp that will tightly control the bass,but not overpower the tube amp.
The MK V is listed at 75 watts,some say more like 90-95 watts. Any ideas for a match to make a great pair would be greatly appreciated!

Hello, I see all these references to McIntosh MC275 different versions. I wish someone could run thru (for me) any chronology and what the differences are (how to tell one version from another). The versions I am aware of are:
1-I'll lump all amps made during the 60's and 70's as ORIGINAL.
2-The first reissue that I know of (a "Gordon Gow" edition)
3-An edition where it has the plastic barrier strip, gold balanced inputs, RCA's below, and black gain knobs, etc.
4-A version where speaker oututputs are newer binding posts for bi-wire, gain knobs are removed, etc.

There are probably a few versions I may be describing here, so any info on full list of versions and or links to that info would be appreciated!
