best amp for Magnepan 3,7

Cary 500MB's.

thank's for the responses

I have heard the little magnepan 1.7 with Jeff Rowland 312 (class D) Corus + dCS Puccini & clock

I was shocked how good it was ...

this would confirm the statement from audio Research chief tester reported here by Stewart

now I wonder what would bring class A amplifier ?

the Sander looks interessant too

Unfortunately, the 3.7 can't be bi-amped, otherwise I suggest Threshold S500 for LP 700Hz with Bryston 10B.
I also suggest CAT SL1 Sig. MK2 for pre-amp.
I am using these audio gears for my Magie system consisting of Tympani IV bass panel and MGIII.
My room is 6x8 m with 2.8 m ceiling height, the sound is fantastic.

I just purchased a brand new Conrad Johnson Premier 350 SS amp to drive my Maggies. Eager to how it compares to my VAC 300.1a.

CJ 350 is the cat's meow. Sweet treble plus absolute punch.
