Designed by renowned audio engineer Darren Myers, the PS Audio PMG Signature Phono Stage is a zero-feedback, fully discrete Class A preamplifier designed for ultimate analog reproduction. Honoring founder Paul McGowan as the first phono preamp in PS Audio's 50-year history to bear his name, it features a current-mode transimpedance input alongside traditional voltage inputs, eliminating cartridge loading concerns and surface noise while maximizing dynamic headroom.

Built with pure Class A FET/BJT topology, diamond buffers, and direct-coupled signal paths without output capacitors, the PMG Signature accommodates dual tonearms across moving coil, moving magnet, and transimpedance cartridges. Remote-controlled gain and loading options provide seamless adjustment directly from the listening chair.

KEY FEATURES

• Zero-Feedback Topology: Proprietary zero-feedback architecture separates surface noise from musical signals while preserving transient detail and dynamic impact.
• Current-Mode Transimpedance Input: Specialized transimpedance input path for low-output moving coil cartridges that eliminates conventional impedance matching requirements.
• Pure Class A Discrete Design: Built entirely with hand-selected discrete FETs and BJTs without integrated circuits (ICs) or capacitors in the output signal path.
• Dual Inputs & Remote Control: Accommodates two tonearms simultaneously with full remote-controlled adjustment of gain and impedance loading settings.
• Fully Balanced Signal Path: Balanced XLR and unbalanced RCA inputs/outputs with zero-feedback folded cascodes and high-current diamond buffer output stages.
• Auto-Voltage Power Supply: High-current analog power supply operating automatically on 120VAC or 230VAC (50/60Hz).
