Orange is the new Blue!

By now it is fully clear to A/V enthusiasts that better fuses than the stock ones are simply a must to extract the best performance from all A/V equipment. If you are searching for the best fuse available worldwide, this one is yours!

There is no other tweak or upgrade in this price range that has such an enormous impact as simply replacing your stock fuse with an Orange Fuse. It may seem a lot of money, 159 Euros for a single fuse, but its value expressed in other upgrades easily surpasses the 1000 Euro mark. That is why the price/performance ratio of the new Orange Fuse is simply unbeatable.

It may sound boring that every new fuse is the greatest leap in performance of all new generations of SR fuses, but there’s no arguing: it is true… several experienced beta-testers confirmed the leap in performance from Blue to Orange is far more significant than the – already great – upgrade from Black to Blue. This tells a lot about the effect the new Orange Fuse will have in your system.

While the Blue certainly is a very good fuse, compared to the Orange, the latter really excels in tonal accuracy as well as providing the finest details without the listening fatigue that’s so often associated with “bright” sounding fuses. Of course, this comes on top of improved staging and depth of field as well as a new definition of life-like realism combined with an unsurpassed musicality with the correct timbre.

In case there are several fuses in a single piece of equipment, our hint is: start with the primary (main) fuse. This one will carry all current drawn and is the most important one.

Are Orange Fuses directional?

Yes, all fuses are directional.  Electricity should flow from the left to the right when you view the fuse (from the “S” to the “R”).  If you do not know the direction of flow you should listen to the fuse inserted in both directions.  One direction will sound more detailed with a more natural timbre.  This is the correct way.

What to expect during the burn-in process?

Brand new Orange Fuses tend to outperform fully broken in Blue Fuses. With Orange Fuses you can expect a mild burn-in during the first 200-300 hours. During this time you should experience a balancing of the soundstage with improved frequency linearity especially in the mid-range and high frequencies. While break-in time of especially the Black Fuse could be significant, the new Orange Fuse will beat a fully broken in Blue Fuse already, right out of the box. After just 24 hours it really starts to open up, and from that moment… things will only get better and better and better!
