A new cartridge design technology improves dynamic range. These new models (the 7000 and 9000) are a complete departure from the current line current line of Shelter cartridges. Newly designed body, high frigidity, improved front-yoke, larger diameter PC-OCC lead wires wound around the redesigned bobbin. These new concepts and design philosophy allow the Shelter 7000 to achieve new levels of dynamism and quietness for a smooth and effortless sonic presentation.
TAS Reviews the 7000
"Shelter cartridges enjoy a reputation for smoothness, vibrant tonal colors, holographic soundstaging, and an eminently listenable sound, but designer Yasuo Ozawa hoped to give his new models "more life" - meaning more detail, transient speed and explosive dynamics. Those qualities are exactly what Shelter's 5000 and 7000 deliver, thought the latter justifies its higher price by providing more finely resolved and open-sounding highs, more potent, refined bass, and greater dynamic poise." — TAS
