Living room receiver/speaker setup question
I brought "Klipsch Reference Theater Pack 5.1 Channel Surround Sound System" for our living room and I am thinking which is the best Sony receiver compatible with it among these two - "STRDH790 - Sony - 7.2-Ch. with Dolby Atmos 4K Ultra HD A/V Home Theater Receiver - Black" or "STRDN1080 - Sony - 1155W 7.2-Ch. with Dolby Atmos 4K Ultra HD HDR Compatible A/V Home Theater Receiver - Black". Also, in my media room, I have "Yamaha RX-A2080 9.2 channel" receiver. Some folks are saying I do not need another receiver for my living room. Is that true? if not, can someone please suggest which Sony receiver would be better? I would want to go with STRDH790 as it's the cheaper one and supports 7.2 as well.
