Yea, I already had iron chokes and an expensive power conditioner before I tried star quad. The power conditioner is still in place but the chokes are gone.

My first pair was on my studio monitors and the difference was dramatic. Easy to compare by trying one first.

I also tried making a star quad power cable for my subwoofer — lots of those around here for sensitive equipment — but that had no effect.
