Hi Fi Tuning Supreme fuse-Burn In?

Update: The HiFi Supreme silver Gold fuse pushed the upper mids too high in my system. I am using Maggies hooked up to a Rockna wavelight. I tried swapping cables etc, but just couldn’t compensate for the additional energy in the lower treble/upper mids.
Having said that, I found a very good match for my system...A Gustard Hifi Nano copper fuse. Got it shipped from China. $25 Just an excellent fuse that brings out the very best in my system, very balanced sound without any peaks. Resolution is on par as the Supreme if not higher. Treble is just liquid, flows  without any glare. 
I will at some point try out the HiFi tuning supreme Cu fuse, the copper should be a good match with my speaker setup. we shall see....
The AG/AU supreme fuse is a very good fuse, but it must be carefully matched to the system, it will probably work very well with systems that are inherently on the warmer side.

Update Again:
Turn out  when I was trying out different fuses, I had accidently installed the Supreme fuse backwards, Treble became piercing. Just noticed it, and after the correct orientation, the upper-mids problem is completely corrected. The fuse sounds amazing again :))))
Sorry for spamming this thread, but this has been a  wild roller coaster ride. 

Final update on the HiFi supreme silver/Gold Fuse: I kept hearing an annoying treble spike on my speakers, stage  was getting too crowded at times, drops in resolution.....basically getting ear fatigue. This  was  why I kept trying to find a calmer fuse, maybe something gold plated. 
Turns out the culprit  was a cheap 50 cent DC power connector in my audio chain (tin plated God knows what), replaced it  with a pure copper Gold plated connector, and Voila!!
DAC has its top lid screwed back on, and the Supreme is staying on for good. 
This fuse  will expose any chinks in the audio chain, but  when you get it all figured out... the end result is just incredible. 

I have a supreme cu on order, based upon @lalitk recommendation.

I’ve tried many different fuses, and many of them cause listener fatigue over time because they are too bright. They push the upper mids and highs.

Spectacular at first, but quickly becomes tiresome for me.

VH audio feels hifi tuning supreme fuses improve musicality without the listener fatigue.

Based on my listening impressions after trying variety of fuses, Supreme Cu is by far the best fuse for digital components if you’re after organic and slightly warm sound…zero listening fatigue.
