Thanks John. I experimented with 60 and 80. I find that 60 seems to sound a bit more full and round, but at the expense of "clean" and crisp upper range as you indicated. I also "upped" my sub setting from -5 to -4, and that seems to add a bit more satisfying punch.

What is the general opinion of the audyssey automatic set-up? I don't have a centre channel yet. Was thinking of getting the VP150 to pair up.
