Hello, I am in the market for upgrading my old Integra DTR5.4. We bought the house we are currently in so the entire system came pre-installed with the house. We just upgraded to the new Samsung QLED Q90T tv so we need a new receiver to hook up to our system. I am not really fond of audio systems/receivers so I went to my local BestBuy who sent out a guy to come to take a look and recommend us systems. The two recommendations he came up with were Denon AVR-X2700H and the Marantz SR5015. Unfortunately, right now the X2700H is out of stock so I kind of feel pressured to go for the more expensive receiver but would like input from knowledgeable people. He had also mentioned we could opt for the cheaper Denon AVR-X1600H. From what I know we have 5 speakers with 1 subwoofer (I think like I said not too sure). The only thing I see the difference between the two receivers is the power delivery. What do you guys think of these two recommendations and if need be should I just opt for the cheaper option? I know the information given was little and to be honest, I have zero clue what speakers/sub we have. All I know they are Sonance speakers and Subs and on the back of the sub I see "Sonance SON OF SUB" with a power rating of 115/230v - 60/50hz 300W which is powered via a power cord connected to the wall.
