I'd have to agree on this one. At my workplace we had (at one time) the Athena sets that included powered subs for every channel. Testing both ways with various crossover points, myself and a couple of my coworkers came to the conclusion that the sound was more solid using the channel preouts to the channel subs and the dedicated LFE preout to a standalone sub. Using all channels for LFE was tremendous for movies, but for music, the sound was a little thin without the subs on each channel.
