I use Wayne's M-80 IC's to my four MB-100's. AP 9's and 12's bi-wire to my speakers.
And, yes, Curt is a super guy. He "fixed" up one of my MB-100's (UPS strikes again !) which I had bought used. It was the "pros at UPS " which made some loose transformer bolts even moreso. And he personally called me to inquire if the damage was pre-UPS or not --- really went out of his way to make sure his product left Charlotte per spec.
That level of service truly impressed me.
