I'm thinking about breaking the bank and adding a new receiver to my setup, but I need some help. I have a Def Tech ProCinema 100.6 with C2 center channel and I'm currently running them off of a Pioneer VSX-510D. First I'll list the receivers that I'm taking into consideration: Denon AVR-3802 Onkyo TX-DS797 Outlaw 950 If I decide to save up a little more: Denon AVR-4802 Onkyo TX-DS898 Marantz SR-8200 And my questions... -First off, will I be able to notice a large improvement between my current receiver and the first group of receivers? -Which of the first set of receivers would best fit my speakers? -And then finally, would saving up for one of the second set of receivers be worth it, or would it be overkill? And if it's worth it, which receiver would best fit the speakers? Thanks in advance.
