Magnepan 3.7i Amplifiers Aesthetix or Modwright? Thoughts?

Have a McIntosh MC-602 amplifier running them now, looking to up the game.  I currently have an Aesthetix Rhea Signature and Calypso Signature, so naturally looking at the Atlas Signature.  The Modwright KW-150SE running as a monoblock via a bridged config though sounds compelling.  Obviously, I would need to demo these.  Question:  Who's got experience with either of these running tough 4ohm loads?  Maggies want serious current, and both of these probably would fit the bill.  My guess the Modwrights may be a bit more airy, which is great, but looking for better control of the bass from 100 down.  Any experience or thoughts shared would be most appreciated!   Thanks!

You may want to consider Bryston,that is the amp Magnepan reps use to demo their speakers.

I have not heard those particular Mac models but the Bryston 7B series monoblocks would be good options. I wouldn't consider them an upgrade per se but more of a lateral move with a different sound signature, e.g., tighter bass, more balanced and not quite as warm. I personally prefer the Mac house sound. You should definitely try it in your system before making the switch.

Still possible to biamp the 3.7i?  I'd recommend Pass Class A on the top end, and then a quality Class D for the bottom.  Sweetness for the highs and middle, tightness and power for the bottom.  But I guess that would take an active crossover, which would be a pain.

The current .7 Maggies have series cross-overs, consequently they can NOT be bi-amped (without serious surgery). The .6 and earlier models have parallel cross-overs, so can be. It is for that reason Maggie aficionados who prioritize bi-amping prefer the .6 models.
