CLASS A AMPLIFIERS

Aldavis

The attached website (http://sound.westhost.com/class-a.htm) has a pretty good explaination of class A amplification form a lay persons perspective. I believe the Gryphon is designed as a push-pull topology (unsure) versus the Pass which is a single ended topology and depending on ones definition of pure class A the Gryphon may or may not fit the bill. But again I am not an expert on the subject.

Unsound I believe krell is a class a/b design

Chuck, all early Krell's were Class A. Some newer ones (IMHO the only real Krells) are as well, but, use their proprietery sliding bias scheme. I still think these sliding bias amps can make good on their Class A claim. The very early Krells used fans, the later ones used massive heat sinks and the newer ones sliding bias, (still pretty hefty heat sinks as well).

I went to krells web site and he states class A topology. It would be interesting to know if it is push-pull, single ended or what specific design they are.

Chuck

I'm pretty sure its push pull. Other than Pass and Monarchy I don't know of any other single ended Class A solid state amplifier manufacturers.

Unsound

That would make sense given the power output. I am sure the Gryphon is as well. It is interesting stuff as I have always found circuit design especially for audio interesting. I majored in Mechanical Engineering as I never had a mind for electronics even though I do enjoy it as a hobby.
