The PW1 “Phono Wizard” is a high-end solid-state phono preamplifier developed by Grimm Audio co-founder Peter van Willenswaard. Designed to capture the musical engagement traditionally associated with exceptional tube phono stages, the PW1 combines a minimalist circuit architecture with carefully optimised power supply design and component selection to deliver a spacious, detailed, and highly involving listening experience.
Developed specifically to address the demanding requirements of modern MC and MM cartridges, the PW1 provides the substantial gain required for low-level phono signals while maintaining transparency and musicality. Rather than focusing solely on measurement performance, the design philosophy centres on optimising the electrical environment of every active component, resulting in a balanced and natural presentation with excellent rhythmic drive and detail retrieval.
The PW1 is housed within a compact chassis featuring a copper-shielded interior and includes flexible cartridge-matching options through adjustable gain and loading settings. Balanced and unbalanced outputs ensure easy integration into a wide variety of high-end audio systems.
