QSA 10x38mm Fuses

Like the smaller 5x20mm fuses, QSA's 10x38mm fuses are treated with their proprietary MMMAT and MAT processes. Same technology, larger form factor for components that use the 10x38mm size — typically power amplifiers, power conditioners, and some larger integrated amplifiers.

The Technology

MMMAT (Musical Metal Molecule Alignment Technology) creates more efficient electron flow through the fuse element, providing greater conductivity and eliminating narrow-band distortions. MAT (Metal Active Technology) addresses the metal structures at a molecular level. Both processes work together to produce a fuse that measures as a standard protection device and sounds dramatically different from one.

"Many high-end audio tweaks I've heard sound great, but none have matched QSA's remarkable performance. I repeat, none." — Clement Perry, StereoTimes

Available Levels

Yellow through Gold, same hierarchy as the 5x20mm fuses. Start at Red or Black/Red if you want to hear what QSA does without equivocating. The Yellow is meaningful; the upper levels are significant.
