If you don't have a Class A amp you a not with us elitist snobs, that's the difference.
Actually difference between class A and AB?
Class A amp sounds like holy grail of HIFI world.
But class A amp are much heavier, more expensive and rarer than class AB or class B design. Few can afford 100 LB weight of a 2-channel 100w/c amp.
Is there any actual difference between class A and class AB when listening to actual music? And what is that difference?

Nelson Pass wrote a nice paper on this - its available on his website. http://passlabs.com/articles.htm Peter |
The difference if fairly simple. Class A amps run at full power all the time. Class B amps run 'on demand'. Class AB amps usually run in class A at lowest power, then switch to class B at higher power. Whether one is better than the other is hard to say, largely it depends on the individual design. Personally I use 30wpc Class A tubes and it, to me, is far superior to anything I've owned in an AB design. But that's just my opinion. |
