Fezz Audio Argentum X10 Step-Up Transformer

🧾 Overview

Fezz Audio Argentum X10 is a no-compromise high-end MC step-up transformer that boosts low-output moving-coil cartridges for use with 47 kΩ MM phono stages. It uses 99.9% pure silver windings on a nanocrystalline high-permeability core with dual shielding for ultra-low noise, wide 8 Hz–110 kHz bandwidth, and <0.01% THD. Passive, no external power required. Sources: SoundStage Global; dealer/manufacturer listings. :contentReference[oaicite:0]{index=0}
