Grimm Audio has unveiled the PW1 MC/MM phono preamplifier, a meticulously engineered solution designed to deliver top-tier audio fidelity from any compatible cartridge. Crafted by Peter van Willenswaard—Grimm’s co-founder and acclaimed “Phono Wizard”—this high-performance compact phono stage is built on minimalist principles, leveraging ultra-low-noise FET amplification and true zero-feedback architecture to preserve signal purity. With separate amplification paths and RIAA correction stages, the PW1 ensures every nuance of your analog collection is reproduced with extraordinary clarity and presence.

Every component within the PW1 is hand-selected and rigorously tested to meet Grimm’s reference-grade phono topology. Housed in a sleek 100 x 100 x 250 mm aluminum chassis, designed by Michiel Uylings, the unit integrates a custom low-noise transformer and copper sub-chassis for superior shielding—eliminating the need for an external power supply. Users can tailor the load and gain settings via a convenient sliding panel underneath the unit, making the PW1 compatible with a wide range of cartridge types, from moving coil to moving magnet variants. The inclusion of both RCA and XLR outputs enhances system flexibility and ensures balanced signal delivery across setups.

Described by Grimm Audio as having a “spacious, detailed, and emotionally involving” sonic profile, the PW1 stands out as a compact phono stage ideal for audiophiles seeking rhythmically engaging analog playback. With an official retail price of £4,695 / €5,000, the unit is available through select dealers. Dive deeper into what makes a great phono preamp in this comprehensive phono preamp guide.
