I know this sounds strange, but try setting the crossover on your fronts to 80Hz or higher. I had the same problem when I had my 950 (I returned it). I first noticed this when playing the Eagles dvd in DTS. With my fronts (NHT 2.5i's) set to LARGE, sub set to NONE, and xover set below 80 Hz, there was a definite lack of bottom end. Setting the xover above 80 restored the bass. I know this doesn't make sense, but it worked for my setup. I'm not sure, but i think I had the same problem playing CD's with the 950 in STEREO mode. I think there might be a bug in the triple xover software. There was a mention of this same issue in a previous thread("need help setting xover"). Give it a try. Good luck.
