This is a little too tl;dr for the gadgets thread, and apologies if the thrad title attracts extra spammers. It can be changed to "Sock Is An Audioignoramus" if necessary.
I primarily listen to music in the car at this point, and occasionally via headphones/earbuds. The last time I bought a home audio system (close to a decade ago), I was miserly, and what I got was absolute shit - got rid of it at a garage sale or something. Since then, I've used various portable speakers with Bluetooth, and while the sound is there and the range is decent, it doesn't fill the room, even when I use a 2-speaker system (granted, the one I have doesn't allow for proper separation).
I started looking online, and it struck me that I thought the technology would've been more advanced by now than it is. Anything within a reasonable price point is still hard-wired, whereas I thought home speakers would just use Wi-Fi as a matter of course. Fuck flying cars; I thought this was a modest expectation. Anyway, I can deal with the wires, like a fucking refugee, even 4 plus a subwoofer, whatever.
All I want is a basic amp/receiver and speakers for a nice sound in the living room, which is around 24x24 feet (7.3x7.3 m) with vaulted gable ceiling about 16 feet (5-ish m) at peak, down to 10 feet (3m). Connecting it to the smart TV and a little record player with digital output would be nice, but just gravy - although surround sound for movies would be intriguing. I don't care about CDs or DVDs much at this point, and could do completely without them, as part of the basic audio system. Just Bluetooth for the iPhone.
Specifically, I listen to jazz-rock fusion, some classical, "world music," and both classic and neo-prog, a lot of it with the newfangled losslessness, so I want to hear crisp sound at all levels that my aged ears can still pick up. I don't need colon-vibrating bass, although I
do want to hear the bass line & drums clearly, cutting through the upper levels without drowning them out, like they're supposed to.
I asked Jeff Bezos about it, and he suggested a haphazard pile of shit, all of which had some sort of drawback or uncertainty. I'm p. sure that nobody except a few trusted souls at

can guide me properly.

Help me, Free Thought Talk Forum And Chat Emporium, you're my only hope.
