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!

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.

I’ve been powering my older 3.6 Maggies for 10 years with a pair of Bryston 7BSTs (a long time for me to stay with the same components). Aside from the well known, slightly weak low bass (compensated for in my system with an REL Stentor sub), the Brystons allow the Maggies to be everything they’re meant to be, with ease—a textbook example of clarity, immediacy, spacial definition, detail, end every other quality the speakers are designed for, with power to spare. My equipment predates yours by many years, but I’ve never had (nor heard) an amp/speaker combo that sounded better, certainly nothing near their price point. Some day, when I update to the 3.7 (or, in my dreams, the 20.7), I’ll stick with my trusty Brystons (though perhaps in a more modern incarnation if I win the lottery).
