Sumiko - Wellfleet - Moving Magnet Cartridge

The Sumiko Wellfleet elevates the acclaimed Oyster Series with a highly polished Nude Elliptical stylus that delivers greater speed, precision, and musical realism. By reducing moving mass and eliminating the bonded stylus interface, the Wellfleet retrieves finer detail while presenting a wider, deeper soundstage with exceptional image focus and effortless musical flow.

Handcrafted in Yokohama, Japan by the master cartridge builders at Excel Sound, the Wellfleet combines premium materials with Sumiko's proven moving magnet design philosophy. Rich tonal balance, refined transient response, and outstanding tracking ability allow vocals and instruments to breathe naturally within an expansive, highly detailed presentation that remains smooth and fatigue-free.

As part of Sumiko's versatile Oyster Series, the Wellfleet offers complete compatibility with interchangeable replacement styli, providing an easy upgrade path while preserving the exceptional musical character that defines the series.
