Hi Randy, sorry to hear about your luck, hope it gets fixed soon. I have the MPS1 and have a 20x15x8 Ht that is totally dead, i.e., soundblocked, cloth walls etc. I was driving the Klipsch Rf83 with my Yamaha Rxv2500 as pre/pro to 100db with no probs..volume would be at up to -2 depending on source recording. Then added the EMO DMC1 and now the Eagles Farewell tour DVD for example plays at 95db at a setting of -32!!!!..lol..so something is different on the Yammy, I was at -6.
I will let you know how the MPS1 handles the M80's when I get them on Thursday although I may not be cranking them to 115 db at my listening position which is 12' from the speakers. I like it loud but, holy moly? I may try it out though and see what happens.
Hope you get it figured out

Regards, Chris
