MasterPhono is expected to ship in June 2023.

Designed by analog wizard Peter Madnick the MasterPhono brings you even closer to the sound of the original recording. This remarkable phono stage offers fully discrete processing from input to output, with both single-ended RCA and balanced XLR outputs. With switchable gain options (40db/50db/60db/70db), passive RIAA employing NOS polystyrene and polypropylene film/foil capacitors, and 10 position loading adjustments (including custom), it caters to a wide range of audiophile preferences.
