I owned the 300i and hear the new piece is better sounding and a better value.But really different sound.It's up to you.I think MF will be more fogiving and still have resolution .The Krell will have grip on bass that the MF can't touch but it is (as is all thier AB gear) a bit "etched" and metallic.Not sure if your open to other suggestions but why not the Sim integrated?More expensive is Ayre which is what I would want with the summits.The Krell in fact might not match with ML's.Krell sounds TERRIBLE with Maggies and your dealing with a (simmilar) very resolving speaker.So I'd go MF.But see iff used Sim and Ayre are arounf in shops to audition.Hear fantastic things about Edge gear but iut's nose bleed stuff price wise.But Sim Moon might be alternative to MF you'd like and if you could pony up for Ayre (knowing those who have had all Sim and went to Ayre and never looked back) if you hook up the Ayre stuff you'll find the budget and never look back.But each to his own.I know folks who loved Krell with Thiel when that for me is an ear splitting combo from hell.The Krell might be your ticket.I knoiw it's hard to A/B them or get the gear in same room with speakers but that is trully the best way because your tastes are your own.
