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!

Topology is by far the greatest determining factor in how a transistor delivers current to a load.
Given similar topologies it’s the final stage, "the output stage" that will determine how much current will flow into low impedance loads.
Complimentary class-A/B devices of the same pair numbers, the BJT will deliver far more current into low impedance loads than a Mosfet can.
Again end of story, your making yourself look ****** by saying anything else.
None of this shit has anything to do with the way an amplifier sounds into normal loads. If you are dumb enough to buy Wilsons then you deserve what you get. Ugly enclosures with crappy drivers and ridiculous cross overs.  
@Kosst_amojan, I disagree with your take on the way Pass Labs specs their amps. The independent measurements aren't confusing, the labeling of Pass Lab's specs are.  Nelson Pass's labeling of specs though still then confusing were at least less so with his previous Threshold branded amps. That Pass Labs declines (even upon request) to spec their amps into 2 Ohms quietly speaks volumes.
@Mitch2, with traditional speakers as impedance drops so does sensitivity. The BHK mono's  950 Watts into 2 Ohms is the equivalent to what a 237.5 Watt into 8 ohms amp that could truly double down could provide into 2 Ohms. Even after what seems like PS Audio's underrating of their 8 Ohm power rating , where did the other 250 Watts go?
