These high performance fuses have pure silver element wire and a pure silver end-cap with silver plating, then a layer of copper plating, then a Gold plating. The copper plating keeps the silver from interacting with the gold. Ceramic casing offers superior resonance characteristics.
In our experience the HFT fuses is the highest performing upgrade fuse, and also has the advantage of using a pure silver "element" which will not degrade due to oxidation over time, unlike the copper-based alloy and silver plated elements in other fuse types. Silver oxide is a good conductor and allows the fuse to have a long conductive life.
HiFi-Tuning fuses have a tighter tolerance than standard fuses. A standard fuse typically has a 10% of stated value tolerance. The HiFi-Tuning fuses have a goal of zero tolerance. Care should be taken to order a fuse of the proper value. Check with the manufacturer of your equipment or other information source prior to ordering fuses. If a circuit was designed close the tolerance edge of a standard fuse and regularly goes over the stated fuse rating, a HiFi-Tuning fuse may blow right away, where the standard fuse did not. This is rare, but can happen. We don't recommend using a smaller value fuse, as they will often blow upon insertion. Using a slightly larger value (say 6.3A in place of a 6A) is often OK with a manufacturer, and may meet the circuit requirement and be rated within the tolerance of the original fuse.
We get asked a lot about the "directionality" of high performance fuses. Our feeling is that the only way to reliably tell that a fuse is inserted into a given circuit with the proper orientation is to listen to them both ways. Taking a little time to listen to the fuse inserted one way, then again the other direction often results in a clear answer to the question "which way is best?".
We are an Authorized HiFi-Tuning Dealer. Due to the delicate electrical nature of fuses, counterfeiting, etc., we cannot accept returns on fuses. We do not offer for sale any used fuses that have left our possession in order to protect your equipment. Please review your order carefully and check your equipment for the proper fuse type before ordering.
Don't use 10 cent fuses in your high-end A/V equipment, Guitar Amps etc.. Beware of some commercial fuses with nothing more than gold plated end caps and nice packaging. These are the real deal.
