QSA fuses are an essential tweak to your audio set up. They dramatically reduce the noise floor in your system and independently verified studies suggest these fuses improve performance by 70% to 80% in comparison with the AC power cord offering 20% to 30% improvement.

There are 9 fuses in the range each offering a level of increased performance in your system. The entry level black fuse is the starting point and the gold fuse the top end of the range offers frankly astonishing improvements to the noise floor.

Hearing is believing.

The full range is now available in the UK exclusively from Futureshop.

QSA fuses are designed to dramatically reduce bottle-neck distortions leaving you with an extremely dark, ultra low noise background from which the music can emerge untainted, more dynamic and more alive.

Burn In

Your QSA fuse will take between 24 and 250 hours to burn in with the majority of the settling occurring in the first 72 hours.

Direction

The direction in which the fuse faces is extremely important and is denoted with an arrow on each fuse to guide you on the correct orientation. If you find the sound harsh or bright, simply switch the direction of the fuse.

Technology

All QSA products employ Quantum Science Audio’s proprietary Musical Metal Molecule Alignment Technology (MMMAT) and Metal Active Technology (MAT). These technologies produce a more efficient flow of electrons allowing for greater conductivity.
