Quantum Science Audio Yellow Entry Level UK 13A Fuse
Future Shop are very excited to introduce Quantum Science Audio, the undisputed heavyweights in the audiophile fuse space. With more than 22 years of research into what they call 'Bottle Neck Distortion', QSA products can enhance your enjoyment of your system in a way that is remarkable for such a small component, until recently considered irrelevant by many in the industry. The Yellow fuse is another significant step up from QSA's Light Blue fuse. It may be entry-level by QSA's standards, but it will still outperform fuses from any other brands at higher prices.

Future Shop are very excited to introduce Quantum Science Audio, the undisputed heavyweights in the audiophile fuse space. With more than 22 years of research into what they call 'Bottle Neck Distortion', QSA products can enhance your enjoyment of your system in a way that is remarkable for such a small component, until recently considered irrelevant by many in the industry. Since all current that enters a power cable or component in your system must pass through the fuse before it proceeds, the quality- or lack thereof- of the fuse can make a drastic difference to your system's performance. QSA fuses aim to reduce the negative effects of what QSA describe as 'bottlenecking', which can help your system perform to its full potential.
Much of this may sound outrageous, but only to those who have not had the chance to hear it for themselves. Having conducted our own listening tests, and based on external feedback, we are convinced that these fuses- all the way through the range- offer an upgrade to a system that can match components many times the price.
The Yellow fuse is another significant step up from QSA's Light Blue fuse. It may be entry-level by QSA's standards, but it will still outperform fuses from any other brands at higher prices.
"I can tell you this: many high-end audio tweaks I've heard sound great, but none have matched the QSA's remarkable performance. I repeat, none." (Read More...)

Please note: fuses are directional, so please ensure you install your fuse accordingly. If you are not sure on the correct direction, simply try it both ways- you will be able to hear the difference.

Free Cable Burn-In Service Option Using The Nordost Vidar Machine
Please Note: We are unable to burn-in cables with stripped bare ends or BFA plugs. Cables are burnt-in for the selected time period AFTER your order has been processed. Custom-length cables are burnt-in for the selected time period AFTER they have be terminated by the manufacturer or our engineers.
Our cable burn-in service is a non-chargeable service and is provided by Future Shop at its discretion. We will attempt to fulfil all burn-in requests for the specified time periods. However, during extremely busy periods, we regret we may not be able to meet demand for all requests due to the limited connections available on the Nordost Vidar cable conditioning machines.
We are pleased to offer a free cable burn-in service for this cable when purchased through Future Shop. The Nordost VIDAR cable burn-in machine combines three distinct functions all in one operation:
- It neutralises charges that build up around the cables and the insulation
- It provides a very wide band and deep conditioning into the conductor core, which produces changes in the way signals pass through the metal.
- It ultrasonically conditions the surface of the conductors.
The VIDAR uses a proprietary combination of composite and complex signals to condition the cables. Parts of the signal oscillate at ultra-low frequencies, while other parts are in ultra-high ranges which extend beyond the range of video frequencies. The signal bounces in a ping-ping ball-like fashion from one end of the cable to the other. During the burn-in process, ultra-low frequencies penetrate deep into the core of the cable. The ultra-high frequencies zip along the surface. This method of signal transmission is set up to beat harmonics, or heterodynes, between the two complex waveforms. In the digital domain, this would be referred to as aliasing products. These beat frequencies penetrate all layers of the cable.
The design of the circuitry also has a unique feature which drives electrons above the conductor into the dielectric (or insulation) area. The VIDAR not only sends ping pong signals along the cable, it also sends a similar signal from the centre core to the outer shield in the case of interconnect cables. This function neutralises the electrical charges discussed above.
So, what does that all mean to me?
The end result of conditioning cables with the Nordost VIDAR is improved sound staging, increased detail, and an overall more musical presentation.
