I still have a couple of VPI magic bricks. They are very well made, and look kind of sexy. I remember when they came out, a buddy and I were trying to tell by AB comparisons whether they made any difference. We decided it was important to be able to see them on the equipment in order to get the full effect. (But that was in the dark ages of the 80's; equipment is much more sensitive now.)
We developed on our own "magic towels," thereafter. You covered the top 1/3 of your dynamic speakers with them whenever the speakers seemed too bright. They were amazingly effective.
