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...) Product Review - Clement Perry, Stereotimes - Most Wanted Components 2020, 2021 & Publisher's Choice 2021, 2022

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.
About Quantum Science Audio (QSA)
Quantum Science Audio (QSA) is a company that focuses on designing and manufacturing high-end audio equipment and accessories. QSA is committed to incorporating advanced technologies and scientific principles into its audio products. It aims to push the boundaries of audio reproduction by applying concepts from quantum physics and other scientific disciplines. QSA believe that by harnessing the power of quantum science, they can create audio systems that deliver exceptional performance and fidelity. The company's product lineup typically includes a range of audio accessories. These products are designed with attention to detail and often feature innovative engineering techniques and materials.QSA's focus on incorporating quantum science into their audio solutions sets them apart from more traditional audio manufacturers. They aim to provide audiophiles and music enthusiasts with a unique listening experience beyond conventional audio reproduction.
QSA specialises in manufacturing QSA home audio fuses. QSA Home Audio Fuses are designed to enhance your audio setup by potentially reducing the noise floor in your system. The range consists of 9 different fuses, each offering a unique level of performance enhancement. The entry-level black fuse serves as a starting point, while the gold fuse, positioned at the top end of the range, is claimed to deliver notable improvements to the noise floor. The listening experience is subjective, and individuals are encouraged to audition the fuses themselves to assess the impact on their audio system. QSA fuses aim to minimise bottle-neck distortions, potentially resulting in a quieter background that allows the music to emerge with improved dynamics and liveliness.
QSA products incorporate Quantum Science Audio's proprietary technologies, including Musical Metal Molecule Alignment Technology (MMMAT) and Metal Active Technology (MAT). These technologies aim to promote efficient electron flow and enhanced conductivity within the products.
It is important to note that individual experiences and results may vary when using audio fuses, and personal preferences play a significant role in evaluating their impact on audio systems.
QSA takes pride in its team of audiophile engineers who strive to design top-of-the-line audio products. The company aims to deliver natural sounds, rhythms, and music that resonate with listeners deeply and emotionally. With their groundbreaking science and technology, QSA accessories offer a new generation of audio enhancement, allowing users to experience greater detail and clarity in their audio playback. Quantum Science Audio products are designed to provide audiophiles with a transformative audio experience, uncovering new depths and nuances in their favourite music.

Free Cable Burn-In Service Option
We are pleased to offer FREE cable burn-in worth £50.00 on this cable for up to 96 hours, using our specialist cable burner.
The cable burn-in machine optimises the performance of the cables from day one. This means cables should be near optimum performance mode when you receive them, so you'll be able to make a performance assessment quickly rather than waiting 70 hours+ of usage. The results of conditioning cables are:
- improved sound staging
- increased detail
- overall more musical presentation.
Please select the 96 hour ‘burn-in option’ from the drop-down menu on the product page as this will fully optimise the cables.
Although it is not yet fully understood scientifically, the phenomenon of “cable break-in” has been experienced by many audiophiles. Interconnects, speaker cables and power cables seem to go through a conditioning period when used in an audio/video system and will sound better after many hours of in-system use.
The sonic differences between wiring that is broken-in and wiring that is not, are very audible in high-quality audio systems. The break-in process is believed to be due primarily to current flowing through the conductors of wiring components.
Dielectric stress caused by a voltage difference between the conductors is also believed to be of some benefit. The fact that it takes many hours of in-system use for wiring components to break in is primarily due to the low-level nature of audio/video signals from normal program material.
The cable conditioning machine was designed to produce signal levels far in excess of those seen in normal audio/video system use. Internally, the device contains a sweeping square wave oscillator that drives a very high-efficiency “H” bridge MOSFET switching circuit.
The signal levels produced by the cable conditioning machine are many times greater than that obtained under the most ideal of audio system conditions. The “stress” on the dielectric of the cable is also much higher than in normal use due to the higher output voltage. It should be readily apparent why results with the cable conditioning machine are often quite audible after as little as 24 hours of use.

The seller shipped the product fast as ordered.
The QSA fuse is really worth the money. The SQ improved immediately and got even better once it stabilised.
It is worth the money for such an improvement. I highly recommend it.
