About the Copper Step-Up Transformer
The EMIA Copper Step-Up Transformer is a high-end phono accessory designed for moving coil (MC) cartridges. It features massive Permalloy-cored transformers hand-wound with copper wire and encased in mu-metal shielded cases for optimal noise rejection and performance. Unlike one-size-fits-all SUTs, it is tailored to match specific cartridge impedances and output levels, ensuring the best synergy similar to matching speakers to amplifiers. Users report exceptional quietness, dynamics, and superior sound quality when paired with high-end phono stages and cartridges like Etsuro Gold. A silver-wire version exists for even higher performance.
