Yamaha Amp Nostalgia


I remember the Yamaha C4 and M4 with some nostalgia, as they were beyond my high school student budget, and quite beautiful with their back lit power and speaker selector switches.

20 years later, they seem to be reasonably well bid on the used market, although the lamp lights are often burned out and not easy to replace, apparently.

So last week, I impulsively bought an M2, because it looked even more powerful and more interesting than the M4, and the one I found seemed to be in good shape with working lights.

There is not much info on the web - does anyone know anything about this amp?

Thank you.

Sit - indeed, the L65 were a baby L300 in sound and looks!, I passed thru various B&W models back then but never had the "fun factor" that the JBLs offered.

As an update, I finally received and have tried the M2.

It sounds surprisingly good with my Tympanis.

Not the same transparency or "air" as my trusty Levinson 23.5, but for about 1/4 the value on the used market, I am very impressed.
Does it sound "warmer" than the Levinson? I find Levinson gear to be a little dry.
I have several M2's, including one I purchased new with a C2a in 1982. I found the MX830 cleaner sounding. I think I will try my Yamaha CDR-HD1500 directly into the MX830 (without preamp) and see what it sounds like.

I have gone to tubes with a Canary Audio CA-301 MkII, with Sophia Princess 300B and RCA 6SN7M tubes... very nice improvement over the Yamaha's.

But at the price of used Yamaha amps, they are a nice step in the audiophile food chain.
I have a M-85 and a M-80,along with the matching pre-amps.I am thinking about grabbing a tube amp and an active crossover and try bi-amping my LaScalas.I love it loud,but want to see if the tubes will "air" out the soundstage.Overall the Yamaha power amps are incredible.
