About the SFz-E
The Kondo Audio Note Japan SFz-E is a phono moving-coil step-up transformer (SUT) designed to amplify low-level MC cartridge signals with minimal loss and very low distortion. It uses a multi-layer balanced winding structure, pure silver wiring, a large ultra-thin permalloy core, double shielding, and direct-soldered signal paths to preserve ultra-low-level detail. The unit is intended for use with balanced or unbalanced phono setups and is specified for cartridges in two impedance ranges.
