How to choose the right phono preamp for your vinyl system
he Hifiverse editorial team has prepared an expert rating of the best 2025 phono preamplifiers for vinyl lovers - the costs of equipment of this class seem justified if we are talking about audiophile-class sound. Our rating includes five of the latest phonostages that can turn the heads of even connoisseurs of this audio sector.
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.
