When our front home theater was updated in 2016 the installer used a Sony BDV-E3100. We also updated the front and bedroom TVs; the new 32” bedroom one is an LG smart tv, and the front is a 40” Sony that’s not smart but less expensive, because it’s fed by the smart home theater unit. There’s probably a newer version of each available now, but the same principles apply. With reasonable prices now I might instead go with a smart tv up front as it would be a smidge more convenient when I don’t need the home theater on. The installer simply wired the existing Bose speakers into the new unit, and we stored away the ones that came with the BDV-E3100 as (argueably) they likely aren’t as good as the Bose, esp. the subwoofer.
The only other issue is we liked the old 2006 era Sony home theater’s 6-disk abilities, so favorite music discs could be kept at the ready in 5 slots while a movie was playing in the 6th. It seems most systems today have gotten away from multidisc capability. The new Sony, not being multi disk, is thinner than the old, and takes up less room in the often too hot overhead cabinet, so circulation is better. It also has, like the TVs, HDMI ports that older systems did not. That makes for potentially fewer wires in the snake pit up there.
RV Outfitters in Bend did a great job consulting, modifying woodwork, and installing. If you are looking only to simply swap out the home theater receiver/player, and already have updated TVs, check for Sony’s at Costco’s often best prices. If you are keeping much older TVs and other A/V equipment, bear in mind that newer products often don’t have the old media outputs. You don’t want to go to do the swap and find the cables won’t work.
