I swapped the fuse on my amp. Now it’s got more snap, crackle, and pop than my breakfast. Excuse the pun. Anyway, I now have a ShoonTH 10A fuse on the IEC inlet of my M7 and a ShoonTH 2A fuse on the IEC inlet of my Lumin X1. After 24 hours on each device, I can say categorically that my system is more dynamically alive: cymbal brushes are clearer and bass is tighter, to the point that I can feel it in my torso. Female voices seem to jump out at me, more so than in the past. I find it hard to believe that simple changes such as this can provide such results. Of course Ken Ng at Kinki says that it will only get better with time. Hard to believe. I'm curious now if Ken will follow through and offer you review samples. My limited research indicates that such fuses work better with sources than amplification. But I guess the overall synergy of audiophile fuse-enabled devices can benefit the entire chain. No need to respond. All the best, Michael
