Best tweak I have ever used.I would agree with all the reviews,awesome improvements across the board.If they do not make an improvement in your system, just send them back.
In my system the major improvement is a huge drop in the noise floor,and this is with a Shunyata hydra conditioner and FeSi-1000 passive noise isolating material ac cables, plus, an Edge battery line amp. A great product,keepers for sure. Why Ozzy's system is not compatable is beyond me,but again,you have the option of returning if not happy.Good luck...
