Gonk, thanks for the input. As I understand you, until I decide to use my sub again, I can remove the interconnect from the 950 for the sub, and don't need the stereo analog interconnects between the 3910 and 950. Bottom line: I can use the 3910 for both 5.1 channel sound or stereo with the multi channel analog interconnects. The stereo will sound the same as if I had used the stereo bypass with the stereo analog interconnects.
