Argentum X10 is high-end MC step-up transformer. There is not a single compromise in its construction – it has been carefully designed to ensure highest fidelity possible. To create the ultimate step-up transformer we have selected the very finest materials: Argentum X10 is wound with 99,9% pure silver wire on a high permeability nanocrystalline core. To ensure noiseless performance it employs double shielding: high permeability mu-metal magnetic shielding and pure OFC copper ribbon electric shielding. With its careful design, ensuring bandwidth extending from 8 Hz to 110 kHz and THD below 0,01% at rated level it is truly beyond compare.
