Surround Sound Pre-Amp

I'm switching from two channel to 5.1; passive speakers to active. I was thinking of Outlaw 990 for a pre, it has two sub outs and balanced connections. Thoughts? I'm open as to what direction to go here, although my funds are more in line with the Outlaw price or another brand used. Bottom line: maybe two subs and all active speakers in a surround system.

Any and all thoughts on a pre are appreciated.

Thank You
