Whats the difference between MOSFET & Class A, AB


I was wondering what the general difference was in MOSFET amps as compared to Class A or Class AB amps.

For the last few years I have been running a Classe CA 300 amp. A couple weeks ago I had a fuse blow on the Classe and it also burnt out a resistor. Knowing the Classe was going to be in the shop I bought a old CJ Motif MS-100 amp.

Now after a day or two of listening I'm thinking this old Motif betters atleast too my ears the Classe so it got me wondering.

I think that you can get WAY to hung up on circuit topology and device type when implementation of the circuit is most important, once you get past the ss vs tube divide. I've come to believe that there are theoretical advantages that tubes provide that allow most any "good" tube design to perform better w the speakers I have than any ss design, but beyond that I have found that the differences between circuit topology and Class of operation are less significant than I had originally thought. I might be all wet for ss amps, since I have not had much experience w them for the last 5 years or more.
