audiophile fuses for Luxman, Wyred 4 Sound, and Simaudio

I haven't compared fuses. All I know, the Synergistic Research Blue Quantum Fuse comes with a 30 day no questions asked return. So I tried one in my Melody tube integrated amp. It was like upgrading to a $500 (at least) power cord. So I got a couple more. Herron VTPH 2A, same thing. Even my Teres turntable motor controller. Same thing. Huge improvement. 

Another thing, they definitely are directional. In the Melody it was impossible to tell which way the current flows. 50/50, stuck it in. Sounded better but somehow not right. Flipped it around. Sounded incredible. Right away. Even much better days later. But incredible right from the beginning.

No idea if "audiophile fuses" are any good at all. Only know the Blue Quantum Fuse is highly recommended!

A suggestion: Find the HI-FI Tuning, Classic Gold fuses, that Parts Connexion is selling for peanuts(closeouts), compatible with your components. If you discern an improvement/a difference with those, spend more for better. https://www.partsconnexion.com/hifi-tuning-classic-gold-fuses.html

Rustler:
I think millercarbon's suggestion is the way to go. I have indeed tried and compared multiple type of fuses and the Synergistic Research Blue fuse will accomplish what you want. Your music will have a more relaxed flow (less grain) and a better soundstage. The Blue fuse is significantly better than the Hi-Fi fuses. You have superior equipment that deserves a superior fuse.
