A couple of things:
1) quite a few audiophiles have dedicated rooms, most people buying cheap systems don’t, they set them up in living rooms/family rooms that are shared with a tv usually.
2) nobody can correctly setup a room in 10 minutes like millercarbon claims. Millercarbon thinks he’s a gift to us all on knowing everything audio which he is not. The pros take hours and sometimes a couple of days to setup a audiophile system. It’s not just positioning the speakers, it’s room acoustics, listening seat position, and if you get time aligned speakers like Wilson’s, it takes hours just aligning them. If you take millercarbon’s system, it might take only a couple of minutes because you can only get so much out of it3) speaker positioning is an art. There are many recommendations on how to start. You can use the 1/3 or 1/5 start, the Cardas starting location, or Jim Smith’s, all each a little different. Also, these formulas differ depending on the type of speaker you are using. 4) I use Jim Smiths formula for seating distance which isn’t equal to spacing between the speakers
5) most families spend a few thousand on a stereo setup, but the real quality systems cost much more. If you think you can get a top notch system for $2500, save your money and get an apple HomePod. I have 5 systems throughout my house ranging from a HomePod, to wireless peachtree speakers, plus a couple of quality small speakers powered by ps audio sprout 100 integrated amps, but all pale to my much more expensive (50-60x more) dedicated audio system. You can get an enjoyable system for a few thousand $$$$ and I think it’s impressive how some manufactures can build a smaller quality speaker that sounds big, like raidho’s and Wilson’s for example.
