On a speaker thread, someone recently spent $1300. on a pair of speaker isolation products, claiming it took his system to an extremely higher level of musical satisfaction. I can believe it. It is still amazing to me, that people like kosst ( a troll imo ), requires scientific facts to back anything up. A long time ago, Julian Hirsch, compared, by electrical measurements, an inexpensive japanese receiver to a relatively expensive amplifier, at that time, showing how close the two products were. I do not recall if he " listened " to these two products, but I do believe he made the comment, that if they measure the same, they must sound the same. Some people need to wake up, give things a try ( a little fuse test ), and trust their ears. If they are NOT WILLING TO TRY AND LISTEN, how can they make a comment at all ?
