Looking at either the Omni 260's or the OM-7's (maybe even the 9's) to base a 7.1 system on. Had Def Techs for 10 years. Liked them alot. Now have Vandersteen. Really like the pinpoint imaging, but I'm finding I miss the "spaciousness" of the bipolar sound. Just curious what the feedback is. What else did you have, and how would you compare the sound. Reliability, customer service, build quality, the whole 9 yards. I really wish they'd do an Omni version with more bass extension, but for right now, that is the OM series. TIA!
