Aha, now we're talking about amps with attitude...
I have built and listened to Rod Elliot's P3A, Prof. Leach's Low TIM Amp (smaller version of the Super Leach), and those wonderful gainclones. They are all very good, which one you build is up to you....
BTW, someone (i forgot who) told me that ON Semi has stopped their samples program already, that's sad.
Good luck to all of you guys.
