Hi all, i am looking for advice on my current setup. My home setup consists of two Klipsch RP-6000F floorstanding speakers and a RP-500C center speaker connected to the Onkyo TX-NR656 receiver. Unfotunately, due to space constraints in the living room I do not have a subwoofer connected to the system. I have one, but placing it would result in cables across the living room floor. The receiver is connected via the ARC channel to the tv (LG G5). My main question is if replacing/upgrading the Onkyo receiver would make a significant difference in the setup. We mostly use it for gaming, movies and shows. Thanks for any advice!
