Audiophile grade fuses, what are they and what are they used for?
In a nutshell a fuse is:
an electrical device that acts as a sacrificial device to provide over current protection.
i.e. a fuse is something that will blow itself up when electrical current exceeds a pre-defined threshold.
This act of self sacrifice breaks the electrical circuit and this prevents everything behind the fuse from catastrophic damage (i.e. certain death).
An audiophile grade fuse simply put is an item constructed from components and materials with a single goal in mind - uncomprosing audio quality. The term “Fuse Rolling” involves replacing the stock fuse with a different fuse (not necessarily an audiophile grade fuse) to influence the sound signature of the audio system.
An example of an audiophile grade fuse is the TF Series Fuse from Furutech, pictured here.
Whether fuse rolling is something you should consider is subjective. Read on to find out if audiophile fuses is a thing for you.
The review for the Uptone JS-2 has been delayed multiple times due to issues beyond my control. A series of unfortunate events that included my primary DAC developing a fault at the worst possible time. The fault turned out to be a dry joint in the high voltage transformer. Kudos to the Don for the diagnosis and fix!
Unfortunately this long run of bad luck means my perspective on things will be cloudier than usual - any positives I write in this post will be over amplified, likewise the negatives under amplified. The JS-2 was also modified during the system down time. I have spent more time listening to the modified JS-2, and way less time with the stock JS-2. Most importantly, I havn’t auditioned all the PSU that’s available out there - the only PSUs I have tried are an ebay 12V5A SMPS, the HDPlex and this Uptone. Therefore please make sure you take all these into consideration when reading this article.
First up I’d like to show what modifications are made. Local DIY guru Don cut up the top plate of the JS-2 with his trusty CNC machine:
