Heck yeah, agree with this! Speakers can vibrate the table and affect the sound through vibrations in the stylus.

Do speakers close to the wall still have the same affect of not in the corners or ported in the rear? Maybe that's less of a concern. My music/movie setup is in limbo right now. But previously I had bass traps or some sound deadening behind L&R in the corners. Surrounds were wall mounted but not in the corner fully.
