Sure can be.
In my untreated room the sound was beyond compromise - it was completely ruined by reverberation - making a mockery of any equipment 'upgrade'.
Physical treatment of two walls and a ceiling (cork / polystyrene tiles) was enough to kill the reverb - bringing an improvement that no electronic manipulation of the source sound could ever give.
WAF? probably not (definitely not for the real dictator types) - but fortunately I've never had to please anybody else.
I'm in the polar opposite position with the bedroom come listening room.
I choose it mainly because it's out of the way so I can be as loud as I want but its full of soft furnishings.
My partner adds to the problem with soft furnishings like so called teddy bear bedding which she guards and teddys of all kinds mostly that lilo stitch character, some of them 4ft high.
It's carpeted with two rugs and a corner couch which she loves a good "throw over" sheet on.
Her extensive clothes collection has outgrown the wardrobe so they are all over aswell.
I have an sa30 with direc in there but I'm not a fan and always liked the natural sound from source.
Having heard the hifi in the living room it makes me aware how much more it can offer in the right room.
Almost a night and day difference.
Unfortunately I'm torn between two lovers.
I've tried moving her stuff only to find it back out the next day and like most men I only think I'm in control so have given up with trying to compromise.
I did one take the teddy bares hostage and jettison them into the tiny loft but she even found them in there thus my punishment was finding another 4ft stitch on the bed staring at me the following week.
Now with Xmas just passing there's handbags turning up in there aswell.
It's also strange listening to music with a gang of 4ft stitch characters sitting next to you.
It's like they are mocking me whilst taking dominance of the room.
I just know one day there will be small one spinning round on the record player one day.
I'd show you my situation via photo but I'm embarrassed 🤣
It's just like watching her walking around the place listening to music on her phone loudspeaker when she has access to 2 hifis.
She just doesn't care about sound quality.
I'm smiling whilst writing this but it does frustrate me really.
