Tube Monoblocks w/- balanced inputs?


A friend is looking for a pair of tube Monoblocks with balanced inputs to drive his Magnepan 3.6s. He may biamp at a later stage (adding SS for the bass) but is looking for something with at least 100-200 watts.

Any suggestions that he should consider?

I use Air Tight ATM-3 monos---they have balanced inputs-
I also Bi-amp my subs w.Solid state

the Air Tight can run 65 watts triode-(what I use) or 115 watts Ultra-linear

after 25 years, I have found these amps for life-
I used VTL 450's to drive 20.1's, and I felt that I needed two pairs to biamp to make them sing. I don't know about 3.6's. VTL 750's would be great, if set up with true balanced inputs.
Thanks for your input folks - my sense is that, with Maggies, more power is always preferable.

He's confortable buying used & I think was hoping to get a monoblock pair for between $2.5 - $4.5K used.
