Phonostages — Audio Research Reference Phono 10

The Reference Phono 10 is a flagship-tier phono stage from Audio Research, built with an exceptional selectable gain range and an exceptionally wide bandwidth. The Reference Phono 10 represents Audio Research's most ambitious current statement in phono-stage engineering.

Key specs that matter

Two single-ended inputs are provided. MC current-sensing input impedance is 47,000 ohms. Output impedance is 200 ohms single-ended or 400 ohms balanced. Gain is selectable at 51dB (Low) or 74dB (High) - a comprehensive range covering virtually any cartridge output level. Frequency response spans an exceptionally wide 0.3Hz to 300,000Hz within plus-or-minus 3dB - a remarkable range extending far beyond audible limits. Total harmonic distortion plus noise is under an exceptionally low 0.002%. Weight is 10kg.

Sound and use context

Expect exceptionally clean, precisely optimisable phono-stage performance reflecting the exceptionally low 0.002% distortion figure combined with the exceptionally wide 0.3Hz-300kHz bandwidth, representing Audio Research's most accomplished current phono-stage engineering ambition.

Pairing

The comprehensive dual-gain selection accommodates virtually any moving-magnet or moving-coil cartridge, including both high- and low-output designs.

Alternatives

Audio Research's own PH9 offers a more accessible alternative within the same broader phono-stage catalogue.
