I'm buying CD's now that have stereo on one side of the disc and 5.1 on the other and I enjoy them both. If it's just a regular CD I kick the 950 into 5 channel stereo for full benefit of the subs. But regardless of the media, if you have two subs, you'll be sending a single-split bass frenquency to each of them. To me that's not stereo subs, maybe ProLogic Subs if they are 180 out of phase with each other.
