Surround tools for 5.1?

I’m getting set up for surround 5.1 and am interested in what other people are using for bass/speaker management and calibration.

I will almost certainly have some form of analog hardware volume controller (to prevent accidentally blowing my monitors and to allow my DA convertors to work at full bit depth) but I’m looking to do bass management and calibration in software. The Waves 360 collection looks very nice with calibration tools etc. Has anyone used these or can suggest others?
