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 Light Blue fuse is a significant step up from QSA's entry level Black fuse, and still outperforms fuses from other brands at a higher price.

Please note: we cannot guarantee that all fuse ratings will be in stock, so longer lead times may apply.

If you can hear a consistent hum coming through your speakers, whether playing music or when idle, then you may have multiple ground/earth connections in your system causing a ground loop. This ground loop can be fiddly to fix, however, iFi have come along with an intelligent solution to help solve this issue. Enter the GND Defender! By using a specially designed AI Ground Detection, the GND Defender can automatically disconnect the ground on your device if there is a ground loop, eliminating the low hum through your speakers. But it does not stop there, the GND Defender can even reinstate the ground connection to pass current if any faults are detected in your system. This ensures a safety fallback to help protect your equipment.
