Hi everyone!

Perhaps my question was a bit too off topic to be addressed in the "general" section, so I'm moving it here.

Does anyone have any experience with the early eighties Yamaha M4 amp? Any pro's and con's?

I'm offered one in mint condition for just over 350$.
It is said to be comparable to Mc Intosh's and other High-End amps and it's rated 120W + 120W at 8 Ohm and 170W + 170W at 4 Ohm.
Would that be enough power to begin with?

Should I be interested?
