im looking at purchasing Diva's 6.1, C3 and R3 (because of this forum...I hope everyone here isnt from the company) and I was also looking at getting the Onkyo 797. Will this reciever be good enough to run these speakers and a sub. How about these a sub and the rest of a 6.1 or 7.1 setup. Im hoping i dont have to buy a seperate amp. I really no nothing about 4db, 8ohms, crossovers, biwire, money, vacations in tropical paradise...oh im getting off the subject. Anyway any advise from you either technical geniuses / or really good cons is appreciated. (I think...lol) Thanks
