So there's no question I'm an idiot, or should just stop doing this late at night when nobody can tell me not too...

S170. S, not T... so close in the alphabet! Damn!

It is not the S170i upgraded version, but acording to NAD the only change is the three new surround sound formats, THX 2, Neo:6, and some other one i always forget, all of which are for more than 5 speakers.... which I do not have!

If I can get the unit for $5-600 it seems worth it even if it is no longer under warenty, no? It'll kick well (hopefully) for two years until I need to move up.

It is a top of the top system, and I love the sound of it.

As for headphones, turntable, nah, I'm a movie guy! And I live alone, so nobody I care about to bug.
