The new Synergistic Research UEF Black Duplex uses the same technology as Synergistic’s world class SR Black Quantum Fuses. That means the same sound you get with their Black fuse can be had in a new state-of-the-art AC Duplex. The same ultra black backgrounds, the same holographic soundstaging, the same low frequency weight and control and the same linear and refined highs without a trace of hardness despite their extreme resolution.
