Hi
The M4 and M4a's close but the M4a has a lot more ambiance. I beleive the difference in in the two are internal electronic components used.
I use yahoo .jp auctions to purchase things Buyee.JP is the service for allowing bids there.
M5 and m5a amps are similar big difference is the m5a's have balanced inputs like the c7 preamp has outputs for.
The C10/m10 were the last of the series and were not to many produced.
The M10 amp sounds wonderful and in my opinion better than all others I own.
Not had opportunity to listen to any M8's. or a C7 yet. Hope to before my time on this earth expires.
The fans on my units are inaudible.
I have owned both the M22 and M25 but only used a c21 preamp then.
I picked up the M4 power amp. Here are some pics. The owner just gave it to me for around $500. He changed the fans at the rear that the previous owner before him had modified. It makes less noise than before, but still audible. He advised me to get a lower watt fan for the rear as it may run silent. The original fan below the amp makes a lot of noise. There may be an issue with them. As I noticed with the amp the top plate is gone. Under the wooden case the top is wide open. Most likely the previous owner before had removed it to get more air circulation into the amp. There are noticeable static discharge. If I place my hand on the grounding post the static discharge goes away. Gotta figure that out too. All in all, the M4 sounds great!
