The New FEZZ Argentum X10 and X20 are high-end MC step-up transformers. There is not a single compromise in its construction of either unit - they have been carefully designed to ensure highest fidelity possible. To create the ultimate step-up transformer we have selected the very finest materials:

Brief Introduction: the Sagita Prestige Vacuum Tube Project Argentum started with a dream to create the finest MC step-up transformer in the world.
And now, after 4 years of intensive development work, this dream came true. We are thrilled to present the ultimate MC step-up: it 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 extreme bandwidth and THD below 0,01% at rated level it is truly beyond compare.
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.
