The Plinius is Class A AND Class AB. They suggest leaving the amp in Class AB mode when you leave them on. The Amp can be listened to in EITHER Class AB or Class A by using the toggle swith on the front.
Yeah a plinius with a good passive pre amp might be the ticket. I just bought a Plinius 100 mrk III used and I will be running it in balanced mode through an adcom 750 in passive mode. The adcom when reviewed by Wes Philips compared it to a 6500 Mark Levenson pre amp. When in passive mode it let's the signal go through unmolested.
