Thanks for your input. I got an PI- 8 and put it it the source rack and I got a PIMM for the amps. I want to get another one so I have one for each amp but all that seems to come up for sale are the MM versions the one I have is an MM2. I have heard that the difference between them was they kept the unit the same but upgraded the supplied power cord. I have not been able to get a straight answer on this weather the actual units are any different and being that its a left channel right channel situation I cant take the chance. Any thouhgts
