This is exactly the choice I'm making right now, although I'm planning on matching whatever SET amp with a pair of Cain & Cain Super Abbys. I have an SLI-80 that I love and have preferred the lush, warm sound for most things, but have also tube-rolled the input (Siemens & Halske) and driver tubes (Sylvania 6SN7GTA and GTs, Tung-Sol roundplate) to create a more resolving sound, which works well with some choral and orchestral music I listen to (mainly, I listen to Renaissance choral, symphonic orchestral, and Romantic Italian opera).
Can anyone characterize the differences in these two SET amps and what their relative flexibilities might be re tube-rolling? I know the AA PX-25 uses KR output 300Bs, but I don't know how much the other tubes affect the sound. And I plan on using Western Electric 300B tubes with a Cary 300 SEI, if that becomes the choice. I assume I can play with the 6SN7 tubes it takes?
Finally, I have a Cary 303/300 which I understand can work very well with the AA PX-25 (becasue the 303/300 produces up to 3 v output via the RCA connections, it's feasible for the player to drive a power amp directly--the AA PX-25 has a .7v input sensitivity).
Can anyone elaborate on your assessment and knowledge of the differences between these two amps?
