Amp Specs. Semiconductors:Transisters......44 Diodes........................66 Amplifier Section Circuitry.......2-stage Differential push-pull, 2-stage Darlington connection,parallel push-pull,direct-coupled OCL(Class-A operation) Continuous Power Output from 10 Hertz to 30K Hertz(Both channels driven)...30 watts per channel(2) Frequency Response.......2 Hertz to 150k Hertz. Etc...Etc...Etc... There is more information about this vintage dual-mono power amp but I think my questions can be answered with what I've given.My question??? Can this amp measure up to amps with similar specs that are made these days? And...what is the difference between "Continuous Power Output from 10 Hertz to 30k Hertz(30 watts per ch.)" and "Frequency Response...2 Hertz to 150k Hertz"???

This amp is a Pioneer M-22 stereo dual-mono class-A amp.It sounds very good but I have no basis for comparison.

after a little research I think you've got a great amp but maybe a bit under powered for todays speakers. Use it with Quads or very efficient Tannoy's or Altecs. If you don't need to play it loud a class A amp such as this would be a great match for the old Quad electorstatics or with a pair of Stax electrostatic headphones. It probably runs very warm so give it plenty of ventilation....
Headroom is the only reason this amp won't compete with some of the newer designs. I bet in a biamped system it will have a killer midrange.
It sure can if it's a Crown D60Dougman

I'm not sure what amp you're looking at, but if it is what I think it is, a Crown D60, then it is about as good as it gets.

As to the last question, the frequency response is the frequency range across which the amp can deliver a flat output response curve. But the Power output spec is what range that at least 30 w/ch are delivered.

if it is a D60 you are absolutely right but I don't think it is because Crown as far as I can remember wrote their specs much more conservatively and would never make any claims without THD and db variables...
BTW a correction to my prior post ...
I said 10hz-30khz +/- 3db would be good I meant to say .3 db

who knows? is the answer...specs say very little when it comes to sound...I think you need to reveal a bit more like what is it? Is it truly a class A amp or an AB that runs in class A some of the time as most AB's do. If you tell the brand and model chances are someone here has some experience with it. But yes it is possible that it will blow away some of todays gear. As for continuous power output that says the amp will produce it's rated power over the range of 10hz - 30khz usually + or - some db rating...never perfectly flat. If it does this +/_ 3db that would be a good spec. Frequency response means that the amp will pass a signal thru the entire range of 2hz - 150khz but doesn't say again at how many db it varies over that range so again not enough info. Not good ... not bad. Many manufacturers play a spec game which is very easy to do and have no relevance to the sound of the unit.
