Dear Peter, When you mention an "M-05" amplifier, are you referring to the PIoneer Exclusive M5? If so, can you tell me what you know about it? I have a chance to purchase a pair of Exclusive M5a monoblocks but no chance to audition them, as they are in Japan. From what I can read on Vintage Knob, they should be/have been extraordinary. The M5 and M5a appear to be identical save for the fact that the latter offers balanced inputs.
