I think acoustic panels can be considered components, and they add to a room. Two well placed $200 panels will impact a system more than $20,000 of cables.I am glad to concur with this advice....Save for the fact that i know for sure that you dont give much credit to cables upgrade in pure S.Q. improvement like myself to a point ... Then i must take your post with a pinch of salt.... Anyway i concur with you for their usefulness... i will only add that sometimes adding panels is better than a new costly amplifier upgrade.....

Now i try to calculate what we must pay for a benefit in upgrade on par with my active room tuner the mechanical Helmholtz equalizer?
In all audio thread acoustic is the sleeping princess.... But all people bet on the working dwarves....
