For many generations, vinyl playback has remained a cherished pursuit for true audiophiles and music lovers alike. Despite advancements in high-performance digital audio systems, the charm and magic of LPs continue to captivate audiences worldwide. There’s an intangible quality to vinyl that digital formats still strive to emulate, making it an enduring symbol of authentic musical experience.
The Vision Behind the PW1
At the heart of Grimm Audio’s philosophy is a deep appreciation for the unique qualities of vinyl. Co-founder Peter van Willenswaard has dedicated his career to designing and refining phono preamplifiers, exploring both solid-state and tube-based approaches. Among all stages of audio amplification, the phono stage presents the greatest challenge to engineers. This is especially true for moving coil cartridges, which produce incredibly faint signals sometimes as low as 50 nanovolts that require amplification of over 90 dB to be usable.
A Sound Philosophy Rooted in Elegance and Precision
Peter van Willenswaard’s approach to the PW1, affectionately called the “Phono Wizard,” emphasizes achieving a harmonious balance rather than merely minimizing distortion. His goal was to develop a solid-state preamp that rivals the sound quality of his best tube-based designs. He believes that the essence of a great phono preamp lies in an elegant, minimalist circuit architecture carefully optimized to create a stable and harmonious “electric environment” for all active components. This meticulous design is complemented by a finely tuned power supply, with passive components like capacitors and resistors selected with utmost care.
The Signature Sound
The result is a preamplifier that embodies Peter’s signature sound spacious and detailed yet warm and emotionally involving. The PW1 delivers a listening experience that is rhythmically compelling and deeply immersive, capturing the magic of vinyl with remarkable clarity and presence.
Design That Reflects the Quality Inside
The industrial design of the PW1 is crafted to reflect its sonic excellence. Michiel Uylings of MU1 fame envisioned a simple yet powerful cabinet shape that complements the preamp’s high-performance internals. Grimm Audio’s dedicated design team further enhances the aesthetic by creating a copper-shielded interior that doubles as a piece of art. This combination of form and function results in a product built for generations to come.
Versatility and Excellence in Connectivity
The PW1 offers inputs for both moving magnet (MM) and moving coil (MC) cartridges, accommodating a wide range of vinyl setups. It features outputs on both RCA and XLR connectors, providing flexibility for various audio systems. Thanks to a superiorly shielded power transformer, the need for an external power supply is eliminated, ensuring a clean, noise-free signal path.
