Arenith…
Here you go…my lil ole .02
So I received my SR orange fuses on 9-3-20 from
vhaudio.com …great service thanks to Chris VenHaus
My fuses have been burning in or “sauteeing” since then.
Equipment powered most of the time…and using the Chesky
equipment and cable burn in track on repeat.
So finally now the “oranges are cooked” 
…and have
turned the proverbial corner…and wow…
The increase in “black space” instrumental separation with vocals
well delineated is way much better. Back up choir vocals appear as though layered on risers well beyond the 8’ wall behind my Aria 948s. Out of nowhere crisp clear images with richness…no sterile qualities here.
The Orange fuses add and improve on the blues by quite a bit (my .02)
with “body” that the blues only suggested.
In the overall it is as if I had upgraded every component significantly.
However your mileage may vary (ymmv).
I would venture to say that without a PS A regenerator much of these
improvements may not occur as it has with my system. Thusly
because not all have PS A regenerators results will likely fall
short of my results…Clean power is the foundation for good
audio…
Would my system with the PS A Quintessence have yielded as much?
It made a great improvement yes…but not on the level of my P5…
which later traded in for a P12…The P5 took my system to new heights,
and the P12 much further still…
Then came the Oranges…
So for me in sq here is my experience with the following fuses
I started with HiFi Tuning Supremes on my amp and P12…impressive results.
Then came the SR Blues a lot more detail.
Finally the SR Orange fuses…tops them all in every area…
Again ymmv…
Hope this helps shed some light on the topic…
Happy tweaking all
