Fidelity Research Transformer
Each of the XF-1 step-up units is designed for a particular impedance, thus eliminating switches and enabling you to obtain maximum performance from your moving-coil cartridge. Channel separation is improved by the use of two completely independent transformers for the left and right channels, each with its own double mu-metal shielding. The XF-1's heavy metal housing provides further shielding and guards against vibration, keeping deterioration in sound quality to an absolute minimum. Thick, 0.3 mm diameter parallel windings are used on the primary side, giving a low DC reistance half that of our previous models. This reduces internal losses and results in a higher-speed signal with more information.
