That amp is pretty nice piece, congrats! What are you planning on using as a phono stage, the one that's built into the 800-B or something else? I think the phono stage of the 800-B would limit you to a MM cart, which isn't a problem, just something to keep in mind. Also, what's the budget? I'm sure you don't want to slap $15,000 cart on that thing, but price is a big factor too.
