Ken,
The 300SEI is definitely a step up but I think the SLI-80 is more flexible as it can drive a larger number of speakers. My buddy just bought one and he is bringing it over so we can try it with my speakers. We shall see. Anyway, I use a Single Wire Connection on the AU24 which I think sounds best. Even when I used it with a Bi-Wire speaker, I used a single wire connection with thier jumpers which to me sounded better than bi-wiring. There is a whole write up comparison on their home-page on why you should use a single wire and jumpers. check it out and good luck to you.
