All user reviews of 5/5 for the Yamaha M-4

Bought used, this amp discrete chronologically from 1984 that followed the "pyramid C200" I was surprised by his musicalitsa neutrality and excellent record in all registres.Les highs are natural and trs well kept low if you put a little sauce ..
A precision close to 305 Accuphase, recalling the sweetness quad 606.
In short, he told me bloeuf and secondary amplifier is the one I use in the prem!
I can be lucky but 300 euros occasion, there is not much competition.
