OP
maybe i am biased but i owned SET. my audiophile friend has a great push pull amp well matched with his speakers. sounds very very good, but i still like mine (call it biased) but there is a something i hear on my gear that simply was missing on his.
So, as all people have posted above, SET has limitations. IF one is going to choose on the amplifier alone, then i would say a great Push Pull.
However, i like to point out, if your build your system based on synergy (example, MY 845 tube amp, driving Falcon gold badge and supplemented with subwoofers) then the ball game changes. all limitations of the SET has been addressed. and the glory of the the SET is now on center stage.
before closing, just a few days ago, a non audiophile came over, and he was interested to listen to my gear, so i did a showoff between my SS versus Tube gear, using my Falcon speakers, supplemented by subs. To him, he just wanted the sound of the 845 tube because what he hears it's involving and palpable. more than my SS. I hear it, but for me its a toss up. but for my non audiophile friend, its more than that. he is by profession a music director of a local singer/band who does shows and produces records
