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 - JBL L65 was one of my favourite speakers at that time - I could never afford them (to pricey for a hungry student back then) but had great time with various ADS models as well as an ESS speaker. I heard the L65 with some McIntosh Integrateds of the time (MA5100, 6100 and 6200) - a very sought-after speaker far north of what the L100 could offer.
I have a CA-2010 inyegrated- beautiful to look at, beautiful to listen to as well. Very acceptable mc phono stage, of course not extreme in detail but compensates with its musicality and open relaxed sound. Greta engineering in these old pieces DC offset almost perfect when I tested it a few months ago. Gets a bit toasty though in class A mode. I had a CA-1000 as one of my first pieces years ago, but the 2010 is in a different league all together. Currently having my tech service a C4 to try out shortly.
Flg - The L65s sound terrific mostly for rock and jazz. The 70 watts produced by the CR1020 seem about perfect for sound repro for these JBLs. I tried playing them at a higher volume with a 1000 Watt amp (740-960w at 4ohm)and they could not handle it even though they were the 3d set of speakers connected at the time. Quite good for what they are though. You gotta like the now retro look with the smoked glass tops. The crystal tweeter is special and 15" woofers really pound. Fun, CLASSIC stuff.
