Haha exactly. Listen more and worry less. Most rooms of normal people are not a problem. The only room I've seen which requires a heavier hand in room treatments is @brencho's. He lives in an older El Lay area house with the plaster walls and very inopportune location of a fireplace and door at the first side reflection points. As far as room treatments: Millennium Falcon in glass table, as you mentioned. Not sure if this is necessary since the top of the table is roughly parallel to the plane between the mids / tweeters and the listener's head. But why not? It's a glass top table. Fluffy seat to the right edge of the photo to address the first reflection. Not pictured: open song books on the piano and random crap in top of the piano to address the first reflection on the left side. Blinds in the center behind the speaker to act as a primitive diffuser. Varying the blinds will change the effect. I've stopped caring and don't bother with tweaking this anymore. Controlled dispersion of buttcheek horns means I have to worry less about the side walls.
