After assembling my stereo(2Channel) and having a Vincent 236II for the stereo(L/R) sound and intergrating my video into the system I added my Denon 4802 receiver as the amp if you will for the rear 2 channel surrounds. Im running a 4.0 setup since the speakers are Def-Tech 7000s that have built in subs and are wired in a biwire configuation like any normal speaker with such flexibility. The Vincent has pre-amp outputs so I connected them via rca wires to the Denon into its aux input. Yes both the vincent and denon have volume controls but through experience have set them properly. My Esoteric sa50 is input into the Vincent intergrated and when the moment hits I add the Denon receiver for a 4 channel sound experience(no dsp modes just straight pure direct mode). The speakers are compensated for distance and their is no placement issues. To me it sounds wonderfull and gives my stereo cd and sacd discs a sense of realisim with the rear speakers ever so adjusted as to give a wide and full and to me a real sound as if in a small theater. Am I wrong or dellusional to think this is OK because it sounds great. I was a semi-pro musician and to me it sounds so alive and so much like a live performance. Their is no reverb or echo (Auralex,echobusters around)because like I said the measurements are almost perfect. The room is 22x15 and I sit about 8 feet from the front speakers and 6 from the rear ones. I dont feel I have any phase or distance problems so why does'nt everyone try it- atleast once. I love it. Opinions are welcome and encouraged, Take care, John M.
