Hi all, about 14 years ago I bought a low\/mid end 5.1 Yamaha Home Theater system which has worked fairly well for a long time. I would like to upgrade the Receiver BUT keep the using the existing speakers and subwoofer if possible and I need a little help figuring out what Receiver would work well and why.\n\nCurrent Speakers: Yahama NS-AP8805 \nManual \/ Specs Link: https:\/\/www.manualslib.com\/manual\/340884\/Yamaha-Ns-Ap8805.html#manual\nFront \/ Center speakers:\n40~120 Watts, 6 Ohms\nRear:\n30~100 Watts, 6 Ohms\nSubwoofer:\nSeparately A\/C powered, appears to be using a RCA connection to the Receiver\n\nOne thing I'm not understanding from a lot of A\/V Receiver sales pages is that despite being 5.1 or 7.1 systems, they are only listing wattage per channel but only with 2 channels listed. for example "80 watts per channel into 8 ohms (20-20,000 Hz) at 0.06% THD, with 2 channels driven ". So I don't have a clear picture of how much wattage I'm getting for each speaker, if only 2 are listed. Another thing I'm unsure about is the Ohms listed, and how it relates to the speakers\/amount of speakers I'd like to run. This stuff is greek to me, so I'd love a if someone could help me figure this all out.\n\n\nI don't have an exact budget in mind but would like this to last another 10 years. Primary use would be 4k\/120hz Console games and movie watching. \n\nI appreciate any help on the matter. \nThanks.
