can anyone tell me where to find specs or an owner's manual for a:

YAMAHA NATURAL SOUND STEREO POWER AMP (M-50)

Yamaha is decent sound reinforcement stuff, amp power is usually
underrated, they put out more than the specs say, but it isn't studio
quality, if that's what you're looking for. .

OK, I'll bite. Just what exactly makes a stereo amp of "studio quality"
better than an otherwise excellent stereo amp?

I would concede the Yamaha consumer power amp is not "professional" in
terms of ruggedness etc, also in studio applications I can see that
balanced inputs might be necessary, but for the purpose of reproducing
stereo sound, as opposed to reinforcing it, I cannot think of any
qualities that would make a "studio" amp preferable in terms of sound
quality.

Nope, the differences would be in flat response, slew rate, THD, IMD,
damping, etc, along with other differences not shown in the published
specs.

Maybe you missed the earlier post where someone gave some of the published
specs for this amp. One of them was 0.01% THD. If true, I would think that
would be plenty good enough for studio use, assuming the other specs are
on par with it.

Unfortunately, the published specs have little to do with the sound of an
amp, and THD alone is virtually meaningless unless it is very high. The
Yamaha Natural Sound line was a consumer/home line of products.Yamaha
doesn't claim this amp as being a studio amp, why would you?
Would you use home Hifi speakers as studio monitor speakers? If not then
why would you use a hime hifi amp to power your studio monitors? I'm not
saying the M-50 wouldn't sound okay with some monitor speakers, I'm just
saying I wouldn't buy an M-50 to power my studio monitors and I wouldn't
recommend that anyone else do it. If you just happen to have an M-50 laying
around and you need something to power your monitors until you can afford
something better, then go ahead and use it. :-)
