best amp for Magnepan 3,7

A little apples to oranges, but I happily run my MMGs with a 40 Watt tube amp at very satisfying levels. Of course, it helps that I use a simple crossover to filter out 65hz and below, but that mainly helps clarity. I don't think it makes much difference as far as absolute spl is concerned.

I can't believe I stumbled upon this thread. I also have a part of mg111a's and a Tympani bass panel, although I believe it is a from a Tympani III system. However I have not yet integrated the two.

I'm interested in how you handled the crossover--active or passive, and what you use for crossover points

Rreid01, here's a recent thread on integrating IIIa bass panels with the Tympani IVa, you may find the information useful:

Check this one out. I have one running a pair of big Ushers and it is wonderful. Just noticed this thread is old and I'm sure he found something by now. :o) But maybe it will help other maggie owners.

H2O amps. I used to drive the 20.1 with a ARC Ref 210 and i ended up biamping with the addition of a Pass 350.5. Just got the 3.7 and the H2O packs a lot of punch. The 3.7s really come alive with the H2O.
