You did the right thing, experimenting and you learned...
i did as you...
A bit more foolish though... 😊
Most people who focus on gear or on toy, negliging acoustic dont know anything...
In my living room the two easiest acoustic tweaks I made were to experiment with the angles of the wooden louver blinds that covered big glass windows. There was a certain angle that broke up chaotic reflections but did not deaden the room. The other effective tweak was to distribute small throw rugs over the wood floors between my speakers and the listening chair. This was not a total blanketing of the floor. There is a mix of throw rugs and unobstructed floor. A little creative orientation of the rugs brought an obvious improvement to the sound. To allege that this treatment is ridiculous is well...ridiculous.
