@ericsquires Great thread man!
I found out that a really big "live" room sounds a lot like a bar band venue when i crank up the volume. Some reverb is actually preferable to a dead room. I've had good luck with thick Oriental rugs and hiding sound absorbers behind tapestries.
Because my wife wants things to be "just so" In her great room I've had to forego the ultimate treatments. Someday I plan to build a dedicated man cave cigar friendly old English club style listening room in the basement. The trouble is everything I want anymore costs insane money and I'm not Jeff Bezos.
Dreaming about and working towards the "next thing" is sometimes more fun than the score.
