Upgrading from my old Yamaha (15yrs) two channel to a 5.1 or 6.1 system and need advice please. Looking for a total system (speakers and receiver) cost of around $750-800 but could go up a bit more if I have too. I have looked at the Onkyo HT-760 HTIB and it was decent except for ugly speakers, but would like to do better. I'm considering a refurbished receiver to give me more $$'s to spend on speakers and have seen the HK AVR125 reccomended here. Does this unit have enough power? Comments on it? I have seen the Dayton 100w 10" sub from Parts Express recomended here, can anyone provide links or advice on this sub or others that would fit in my price range? Normally I see the sub installed in the front however in my room I have a perfect corner for one in the right rear. (same wall my couch is on) Will this location be a problem? My sub location will dictate about about a 40' run of cable to it. I have seen some reccomend using 75ohm shielded video cable for this purpose. What is the general feeling, is this going to work well for sub cable? Any reccomendations for good quality/reasonably priced 14-12ga speaker wire would also be appreciated, my rear surround runs will probably be about 30 and 40ft. Sorry for so many questions, thanks for any/all advice.
