Dan the Pav was a class A rated pre-amp as far back as 93.If you really want the best 2 channel your most likely going to have to go tube. I couldn't believe the sound of tubes and the JM Labs Mezzo Utopias.But everyone hears differently and therefore you will find many an opinion. I have wasted alot of money by relying on reviews or other peoples opinions,so i would recommend driving to the different high end shops and just listening to the different options. Bring your own music though.I agree with you on the 7.1 amps they are sweet and i have never had them cut off even at full volume. Good Luck
