CP Tomes's approach will work well with both digital sources (including analog sources that are processed digitally by the 950) and in stereo bypass mode. The subs will of course be active in stereo bypass mode in this scenario.

The only case that might give you some trouble is the six channel analog input - if you have DVD-Audio or SACD and your player does not allow you to redirect the LFE channel into the mains before leaving the player, the LFE track would be lost. If you aren't using the six channel analog input (and a lot of folks don't), this is not a concern and CP Tomes's approach works fine.
