I am upgrading my home theater speakers and trying to decide between 2 different Def Tech Speaker sets. I purchased and setup the Def Tech BP-8060ST System and am pretty happy with them...but...with spending that much money I am trying to decide if I just spend the extra $1300 and get the BP-8080ST System. I am running a top of the line Onkyo receiver so powering the speakers is not an issue. Suggestions should I take back the 8060 while I still have time and order the 8080's or will I not notice a difference between the two? HELPP time is running out fast!
