The Grimm Audio PW1 is a reference-level phono preamplifier built to reveal the full character of vinyl playback. Using a refined solid-state circuit and carefully implemented power supply, it delivers an open, dynamic presentation with the control and quiet background required for high-performance analog systems.
Designed by Grimm co-founder Peter van Willenswaard, this component reflects a long-standing focus on signal integrity, simplicity, and musical coherence.
Reference Phono Stage for MM and MC Cartridges
Flexibility is important in hi-fi. The Grimm PW1 supports both moving magnet (MM) and moving coil (MC) cartridges, with a wide range of gain and loading options for proper system matching.
It accommodates everything from high-output MM designs to low-output MC cartridges, maintaining stability and low noise across configurations. Fern & Roby is an authorized dealer for a number of cartridge manufacturers, we’re happy to discuss options based on your listening needs.
Minimalist Circuit, Maximum Musicality
Simpler can sometimes be better. The PW1 is built around a deliberately simple circuit, carefully optimized for signal integrity rather than complexity.
This approach preserves the structure and timing of the music, resulting in a presentation that is spacious, resolved, and rhythmically coherent—without the softness often associated with more colored designs.
Low-Noise Architecture
Analog lovers know phono signals require significant amplification, making noise control critical. The PW1 addresses this through thoughtful layout, component selection, and internal shielding.
The result is a low noise floor that allows fine detail and dynamic contrast to come through clearly, even with low-output cartridges.
Integrated Linear Power Supply
A custom linear power supply is built directly into the PW1, eliminating the need for an external unit.
This simplifies system setup while maintaining stable, low-noise power delivery—an essential part of consistent analog performance.
Flexible Gain and Loading
We like the PW1 because gain and loading can be adjusted to suit a wide range of cartridges, allowing for precise system matching.
These settings provide the flexibility to optimize both electrical performance and overall tonal balance.
Why Choose Grimm Audio
Grimm Audio applies the same principles to analog as it does to digital: reduce complexity, preserve timing, and maintain signal accuracy.
The PW1 perfectly reflects this approach; it’s a phono stage that prioritizes clarity, balance, and long-term listenability.
