Best 2.1 setup for under $750?

[Howard]

So, this is a thing that I've just realized:

I use my subwoofer as a pass-through with the low-frequencies cut out to the 2 bookshelf speakers. When my subwoofer is off, it still passes the sound through a bit (Not all the way, it's quiet). I suspect this could be an issue? Or is this normal? I find it troubling. So many issues with this whole system.

Probably not. It's a grounding issue for sure.

Rane has a bunch of good info.

I don't know if this has been mentioned but even the cheap Asus Xonar cards have crossover functionality. That way you don't have to use pass-through to your sub.
