I also have the purple fuse on my integrated amp. But I also try the ACME Silver Ag/ cryo, and for the price it is a "wow" effect. You should try on your components.
Sony Hap 1ZES play with SR Purple Fuses
I have used SR Purple fuses on all of my audio components with excellent sonic results. Most every fuse has been installed in the mains/AC line. However, the Sony player only has two (2) internal fuses inside the player. Doesn't seem to be in the power line. I was wondering if anyone knew, if replacing both the internal fuses in the Sony, would produce the same sonic improvements as the other components?
