1972 called, they want their fabric back. You know, I never gave that a thought really. My primary criteria was cheap, then it had to be able to be breathed through and lastly I wanted it to match something in the color scheme in the room. I wasn't trying for an era specific pattern. I know you're kidding but it is something I'll consider in the future ... era specific colors and patterns ... there go my estrogen levels again. :rolleyes: Yeah, the REW method would probably be best. Too bad I'm too stupid to figure that program out.:o Besides, you probably couldn't mount/remove the panels fast enough to make reliable comparisons. There is something to be said for long term comparisons and the subjective analysis. I may have trouble comparing a Brothers in Arms CD played on a Sony to an SACD played on a Denon but I think I am better able to say that I prefer the general sound of panels -vs- no panels ... especially after listening to one and the other for a month or two in the space that I listen to music in daily. Maybe I'll do something this week in honor of Alex. If he does something I normally must do something. :rolleyes: My next move is to get an MP3 player and some headphones so I can call Goodwill to get this sh!t out of my house. :D
