Class A Solid State Sound

Would someone kindly describe the differences in class A sound of Pass XA.8 series, Accuphase A-70/75 series, and Gryphon class A amplifiers. Does much or any of the differences relate to mosfet (Pass and Accuphase) or bipolar (Gryphon)  output devices?  Thank you!

same same, the bi-polar will do more current than mosfet, end of story.


My ME amp, 24 bi-polars (bjt's) per channel, (Nelson Parallel 24 bjt's per channel with one of the Thresholds.)
 
Lets see a Mosfet do 100amps continuous with 12 (six pairs) per side

Guys, it really does not matter. It all depends how an amp was designed and uses these output devices not the actual characteristics of an individual device.

Sorry, wrong!
If you really wanted to be a peacemaker, you should have just posted your first sentence and left it at that.


Cheers George
