Smaller vs larger listening rooms?

My room is 12.5 ft wide x 20 ft long x 7 ft high. Objectively, too low and two narrow for the best sound.

With attention to acoustics, it’s become one of the better rooms and systems I have heard.

The speakers are Janszen Valentina P8. Subs fill a hole in the bass of the main speakers that would be present in any reasonable listening position.  Adding DRC helped smooth the bass further, though it’s better than most even without that.

as @mahgister said, " Hope, listen and be creative" and address the room acoustics. That, almost always, will provide more improvement than gear upgrades, no matter how costly.

My sister was just reminding me of a relative we visited 50 yrs ago, with a big old house with huge living room -- it contained a grand piano and six couches scattered around, as well as the stereo. 10 ft ceilings.

I still remembered how sound from the stereo bloomed in that room.
