Robert S. Youman of Positive Feedback Online (Sept/Oct. 2014) wrote: "...with the RED fuse in place, this was the best my Playback Systems MPS-5 ever sounded. That typical edge and stridency on certain digital recordings was much better controlled if not gone... I could hear into the music with a new level of detail and speed that was easy to differentiate. The soundstage seemed to double in size for both depth and breadth, again, easy to hear and realize...The RED fuses are an absolute must audition...this product is a relatively inexpensive upgrade and can offer clear and immediate sound quality improvements to your system. Very highly recommended!"


"...installed the RED fuses & WA-Qauntum chips over the weekend & the results are amazing. Such a pristine sound!"

"...l've found the reds require a much longer burn in period typical burn in approx 150 to 200 hrs.  Ive used isoclean, hifi tuning supreme, sr20's  and furutech in the past. Once fully burned in the sr red's outclass all the others on every level with amazing detail, clarity and smoothness!"

"...the best hifi tweak I’ve ever made; what a sound!"

"...took a chance with this RED fuse, and man what a difference, took a layer of mud out I didn’t realize was there..."

"...inserted the SR Red fuse several days ago, and thought to myself how great it sounded. Put my stock fuse back in, and was shocked at the collapse of music..."

"...a steal as far as what they do to improve your system!"

"...I took a chance on this SR Red fuse, and it paid off big-time..."

Satisfaction guaranteed - 60-days Money-Back Guarantee

Synergistic Research RED Fuses feature proprietary alloy burn wires and end caps encased in anti-resonant ceramic bodies. RED fuses are then treated with 2,000,000 volts of electricity in a process SR calls Quantum Tunneling that alters the conductor at a molecular level for optimum performance. Unique to SR RED Fuses is a new treatment process applied exclusively to SR RED Fuses that realigns the crystal structure of both the burn wire and the end caps for a refinement in high frequency characteristics and improved timbre linearity. All told SR RED fuses significantly outperform every other high-end fuse on the market and are the only fuses guaranteed to deliver a significant increase in system performance or your money back. When compared to SR’s award winning SR20 Quantum Fuses, SR RED Fuses sound more refined with smoother highs and more linear frequency extension from the deepest bass to the highest highs - no small feat given the remarkable performance of the original SR20 Quantum Fuses.
