Synergistic Research Black UEF fuse, 2, 5, 10 A, 5x20mm slow blow

I only have 10A slow blow, 5 x 20mm fuses. I purchased extras and don't need these. Many rave reviews. 2016 Stereotimes Most Wanted Component.

Synergistic Research BLACK Quantum Fuses ($195.00 per fuse): Tiny fuses are a BIG hit! Who would ever think that two tiny audio amplifier fuses could have such a profound, positive result in what we hear from our audio system? That's exactly what happened when I switched from the two stock fuses that I had been using with my reference Behold stereo amplifier to Synergistic Research's new BLACK Quantum Fuses. Proprietor Alfred Kainz of Highend-Electronics located in California gave me superb service and sage advice regarding the best way to get maximum effect from these fuses. They are directional and require proper orientation to get the best results. In addition, the near super-conductor graphene is used which requires these fuses to have 25 to 200 hours of burn-in time for them to provide their optimum magic. The more the fuses burned in the more the soundstage increased, harmonics grew denser, and grip in the bass became tighter. All of these attributes allowed this listener to become much more emotionally involved with the music. Synergistic Research's new fuses seem to allow the amplifier to pass more important information along and perform at its very highest capacity. At $119.95 per fuse you owe it to yourself to give them a try. The results I experienced are a huge bang for the buck. Highly recommended! (Clement Perry, Moreno Mitchell, Dan Secula and Ron Cook)
