The UltraPhono Pro is a single-input implementation of the flagship MasterPhono's core architecture, built with fully discrete J-FET and MOSFET input and output stages and passive RIAA equalization with zero feedback. A seven-stage regulated balanced power supply, front-panel gain and loading controls, and both balanced and single-ended outputs complete a design that holds RIAA accuracy to within 0.05dB, housed in brushed aluminum panels over a rigid steel frame.
