I have tried both of these fuses and the Hi-Fi tuning fuses are just a little better than the Isoclean fuses, its like getting a power cord upgrade. I also have two Clever Little Clocks and the improvement I'm getting with these are like getting a really good speaker upgrade and on video, it gets you very close to HD TV! P.W.B. ELECTRONICS is the BEST KEPT SECRET in ALL of AUDIO!
