Pictorial Tour Of My Room And Some Audio 'Philosophy'
I go with the philosophy of using just enough 'dedicated' treatment to fix any audible problems. As the room is large - 29 x 11 x 9.5 feet bass boom isn't an issue as the main mode is below what the speakers can output, but high frequency bounce still needs dealing with.
I'll start with the door.
This corner is next to the listening seats so I stuck some of this acoustic foam up as it's quite a lively corner and bounces high frequencies about. Since I need access I can't put anything else here. The tiles are from Studio Spares and are cheap, but do the job.

Corner on the other side, again this was a bit lively hence the roll of insulation.
The bubble wrap is just there as it's a convenient spot to put it, but it's probably quite absorbent too so it can't hurt:

A.V system

This operates across the width of the room with some Beovox MC120.2 speakers
From the top:
Onkyo universal disc player - you got DVD, BD, CD, HDCD, DVD-A and SACD playback with this unit. They don't make them anymore
Pioneer DVD 565-A which is now just a back up
Parasound C/DP 1000 CD player
Technics SH8058 EQ
XTZ A1000D3 integrated amplifer, this has a DAC in it, sound goes in from TV via optical Coax.

One of the speakers for the main system - Speaker choice I find is very personal, I dislike a lot of speakers and others dislike my choices too. I did audition some serious cutting edge speakers like the Kii3 but in the end decided to go 'old school' with a big banger.
The acoustic panels you see here - I can't really tell if they do anything but I had them left over. IN theory they should cancel the HF reflections off the brick wall, with the speaker being so close.
Main corner where it all happens - main system electronics - TEAC, Sony, Krell plus the LP and CD storage.

For acoustic purposes it helps to have a big stuffed bookcase like this in the corner as it scatters and damps high frequency reflections. My one remaining turntable is mothballed so the LPs are not used, bought most of them again on CD.
Opposite corner, again with a stuffed full bookcase albeit smaller. Can't hurt.

And back round again to by the door where I've got some spare kit stored (there's lots more in my upstairs 'showroom' lol

Over almost 40 years and owning and auditioning a lot of equipment I've pretty much sorted out what works for me, so here is my 'philosophy':
By far the most important thing is the loudspeakers and the room acoustics. With a digital source - any digital source even a smartphone - I'd say this is 95% of the sound quality right there.
In particular getting enough damping in the room to stop too much high frequency bouncing about. I find that very fatiguing. Of course you don't want to kill the place dead.
Most of that can be achieved with normal furnishings and then after that treat any still audible problems that you notice. Not rocket science and you don't need to spend a fortune - you aren't making a professional mastering suite (unless you are).
So spend almost all the money on speakers - and carpet, curtains, furniture, bookshelves and so on.
For source I no longer bother with vinyl as it's expensive and inconsistent - although when it's good enough I don't really have any issues with it, I just don't see the point when we have something cheaper and better instead.
Cables - yes mine are quite expensive even though I'm not a believer. I've done my share of swapping the damn things and straining for hear the differences. No longer spend time on that game.
Buy something quality that's not going to fall apart in your hands after a few plugs and unplugs, fit and forget, never think about them again. Just make sure speaker cable is thick enough to avoid any losses due to raised impedance. - that's my philosophy there.
Power - I don't use any power conditioners, regenerators, and all the power cables are just whatever was lying about when I hooked up. I really don't think there is any problem to be solved with such devices, unless you have pops and clicks from the fridge - or whatever -starting up. At least in the UK anyway there's nothing wrong with the mains power and any noise or distortion is removed in the transfer from AC to DC in the equipment's power supply.
Spend the money on better speakers and room instead! No matter what speakers you have there's always something better to save up for. I suppose if you really have have maxed out on the things that matter then it's somewhere else to go, but I'd still advise against it.
The danger of constantly swapping and comparing and upgrading is you forget to just listen to the music - which was the whole original point of the exercise. You can actually ruin that pleasure for yourself by never being able to get out of 'analysis mode.' Ask me how I know!
Anyway, there is my two cents for the day.
