Fantastic amp, particularly when restored and running properly. Big full sound with much detail. Huge soundstage. Teamed up with it's matching C-4 preamp is something to hear.

Probably my favorite vintage solid-state amplifier. I was a tube amp aficionado until I got my hands on a used M-4. This amp gave me confidence back in solid-state gear. I regret selling it and am still always on the lookout for the coveted M-2 (the M-4's bigger brother).

Found mine by accident and it sounds great!
It is partnered to a C2x and the NS1000m which were formerly coupled to a Medevoort poweramp.
Some say I should re-cap it, but first I''m going to enjoy its sound for a few days?

Had this amp back when I was in College, but had to sell it. Just picked up another in excellent condition. Its a great, sweet sounding amp that is under rated in my opinion.
