The Argentum X20 is a high-end MC step-up transformer precisely engineered for uncompromising audio fidelity. Constructed with 99.9% pure silver wire wound on a nanocrystalline, high-permeability core, it delivers exceptional signal clarity. Its dual-layer shielding—mu-metal for magnetic protection and pure OFC copper for electrical noise reduction—ensures ultra-quiet operation. With a frequency response spanning 10 Hz to 100 kHz and total harmonic distortion below 0.01% at rated levels, the Argentum X20 sets a benchmark in performance. It pairs seamlessly with cartridges like the Ortofon Quintet and Cadenza series, Goldring Elite and Eroica LX, Hana ML models, Dynavector, Lyra Kleos SL, and others in the 1.5 to 9 Ω impedance range.
