Synergistic Research SR20 Master Quantum Audio Grade Fuses

SR20 MASTER Quantum are the latest in a range of custom alloy treated, high-end audio grade fuses.

Released February 2023, SR MASTER Quantum Fuses are a German-built, custom ceramic fuse, made from a unique two-million-volt treated alloy. The product address a commonly-overlooked component in the signal chain which introduces noise at a fundamental level.

Master Fuse is an entirely new kind of Fuse; the first Synergistic Research fuse developed expressly for full resolution, dynamics, sound-staging, speed, and impact without the need to create musicality as a system-wide fuse loom.

Master Fuse was designed to work alongside Purple and Orange fuses to create dramatic new levels of sonic realism. Best of all, most systems will not benefit from more than one (or possibly two) SR20 Master Fuses in an otherwise complete loom of Purple and/or Orange fuses. Start with a single Master Fuse on your DAC or line conditioner and realize results. You can then experiment sparingly with additional Master Fuses if you wish to go further. The choice is yours.
