Beyond Ayre Pass and Rowland
What would it be? Transistor or Hybrid. This is a general discussion.
I heard that Gryphon and Ypsilon qualify but I didn't audition either. Lamm hybrid does too, I believe.

Ayre is bipolar output, Pass is MOSFET output & Rowland has been bipolar output in yester years & class-D these days. 

Are these the only 3 transistor brands that come to your mind? There are so many others in the market at different prices. OR, do you want to stay in the Ayre/Pass/Rowland price range?

I'm not sure what the point of this thread is? Do you want to get away from these 3 specific brands & buy something off-beat? Or, get away from these 3 brands & buy some European amp brand? Or, are you looking to change output stage topology? Or, something else on your mind for discussion?
Unhappy or had enough of your present setup? 

These three brands appear to be very popular among both audiophiles and not. I am interested in the experience of those who auditioned other amps that seemed a step or two above. This thread is not about asking a specific advice or about system integration.
Parasound and Levinson are not better in any way.
