Grimm Audio PW1 – minimalist phono preamplifier
The Grimm Audio PW1 phono preamplifier stands out with its minimalist circuitry, aimed at preserving the integrity of vinyl playback. The PW1 minimizes the number of components in the signal path, allowing the music to flow with minimal interference. Each gain stage uses a single active component, while a carefully selected op-amp serves as a buffer to maintain signal quality. The “PW” stands for Phono Wizard, so the PW1 features a wide range of input adjustment options to suit the characteristics of the cartridge.
