Fast forward to today .. planning on partially finishing my basement this year .. no desire to own or set up a home theatre at all.
I have been there myself. I had a "surround" system of sorts in the 80s, using some rears in the old "Hafler quad" setup (tie the grounds of the two rear speakers together, but do not connect them to the amp, which gives the difference signal). It wasn't the best, and probably didn't decode the Dolby surround the right way, but it was still cool. I added on an Onkyo doohickey that decoded Dolby Pro Logic II and had two rear and one center amplifier, so you could use it with a stereo setup. Early 90s on that one. In my last house, I bought a cheap (and nasty sounding) Pioneer surround receiver with a DV578A universal player, with a Dayton sub, and Boston speakers for the surrounds.
Even in my main audio system, I had rears set up with a spare amp, connected to the 5.1 outputs on my Oppo.
All of it sits in the basement now. No desire whatsoever to deal with the clutter of rear speakers, all the wiring, the extra connections and components, and all that. I suppose if I had a larger space I might consider it, but
only for music. The classic films, hockey games and TV shows I watch don't need surround, and I rarely watch TV anyway.
Hence, the soundbar. It does its own "surround" thing way off to the sides, it sounds really good (should be, given its original list price), and it is all in one single unit, with nothing but a digital cable and power cord connected to it. I want to add a really small sub to tuck into a small space, so I can fill out the deep stuff below 40Hz. It's kinda fun playing Smash Brothers on the Nintendo Switch when things are exploding all around the room.
I have a new 65" 4K TV, and I've yet to determine how it affects sound in the room, as it is between my two speakers (they are far out from the wall, though).
