Hi, I found the Audio research mono amps were a fantastic match for the maggie especially in the midrange. The Halco was stunning everywhere. Bass like you would never believe. So fast and it made the maggie sound really vivid.
I really like Levinson gear although I think it is expensive for what it is. That lovely finish I suppose you are paying for too.
Why are you going back to a class a/b amp after classD? Did you need more power or do you just prefer their sound?
A good friend has the 464 monos on some Wilsons. Quite nice driven by the ML 390s direct.
how do you find the nuforce amps with the maggies? I use ICE power Bel cantos amps on Apogees, but I ran various Magnepans for years with all sorts amps Valves, solidstate and class D
