I've successfully used Acme, HiFi tuning, and Synergistic fuses. I've got nearly 200 hours on my Synergistic Purple. In my system, in my opinion, to my ears with nearly 40 years in this hobby, the Purple fuse is one of the most cost effective improvements I've experienced.
It's rank hubris for mijostyn to suggest that I don't know what I'm hearing. And those of you who think that blind ab testing has anything to do with how people actually listen to music, please spare me the tired psycho-babble about self delusion.
