What could I expect to hear from a Class A amp?


I have been interested for some time about what difference a Class A amplifier would make in comparison to what I am currently using. Right now I have a Classe Model Fifteen, which is the best amp I have ever owned...What could I expect to change if I moved to a Krell KSA-200, or even a KSA-50?

I did listen to Clayton's at a show. It blends in among the good amplifiers. It's interesting to note that big players have not caught on to Class A in big ways. May be they figure the R&D it takes to compete against Pass take so many years that it's not worth the risk. The little guys are still at Square One and thus don't have much to loose. Just pondering here.
The 'big players' prefer to sell convenience. IMO, their equipment sounds like it is built for that too :)

So there is plenty of room in the market for smaller companies that base their marketing and products on higher performance features like Class A operation.
Thanks for the knowledge guys! Feel free to keep writing your thoughts. I would love to get my hands on ANY class a stuff just to see what observations I could make...
