Amp for Maggies

I have had great results using a pair of fpb 350 Monos from Krell. I use a separate Krell KSA 150 to run the center and sub but the sub doesn't get much work since the 20.1 Maggies don't crossover to the sub until 40 db. Given that the Krells pump 700 watts into each Maggie (at 4 Ohms) there is plenty of reserve power. I hope you enjoy those Maggies as much as I do. . .they're a bargain if you have adequate room size for them.

PS Audio GCC250 is my choice w/1.6s.
I run them full range w/sub x-over at 45hz.
The PS is an ICE ASP500 module amp.

I have two answers:

1. Spectron Musician III SE stereo amp
2. Spectron Musician III SE mono-blocks

I've owned (and still own) various models of Magnepan speakers. I've used both tube amps (e.g., Sonic Frontiers Power 3 SE, Quicksilver V4s) and SS amps (e.g., Adcom 545, Odyssey amps, and ? - can't remember now) on them. You do need lots of power for Maggies and the model Maggie you choose will impact the power minimums (i.e., 3.6R and 20.1R require massive amounts, while MMGs a lot less) and type of amp (some folks find the ribbon tweeter Maggies more easily sound harsh/strident with low quality SS amps). The best of the lot for me was easily the Odyssey Stratos Extreme monos - warm and musical sound for very little money. Many Maggie owners posting on the Planar Asylum, a very good source for info on this subject, like Pass Labs amps. Switching amps provide the power but the jury is out on whether they sound good. Other factors are your room size (large v. small?) and music choice(s) (rock v. chamber music?). Good luck.

Do consider a Moscode 300 or 600 power amp. It is the best of both worlds of tubes and solid state. But if you want the latest in that group choose the Moscode 401 I believe it is called. Tube and solid state and they all drive the Magnepans very well. The 600@300 watts per channel is a perfect match and will handle the loads you require and 401 is even better than the 300 and most likely exceeds the 600in sound quality but a little less power. You get a very wide soundstage that is magical and a very liquid presentation. You must experiment with cables. Once you lock in it will be hard to find sound better than this. Good luck
