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!

I had KMA 100s. Old Krells are all Bipolar output stages. Wonderful amps until one blew.
 I’ve heard diverse opinions on “pure” (non-bridged) class A monoblock amplifiers (Such as Antileon Evo Monoblocks and others) vs bridged class A Monoblocks (like Clayton M300 bridged internally by the designer or Luxman A600 in BTL mode (bridge tied load) 
Many feel the non bridged Monoblocks are better sounding, when output devices from the two channels are summed in Parallel vs Bridging the two channels.  Thoughts or technical explanations?

Kosst, I thought you were smarter than that, you are making your self look like you have no idea.

Everyone knows given the best implementation for both, the complimentary BJT’s (Bi-Polars) will do current and low impedances far better than complementary Mosfets can. End of story.!!
