Soundsmith Norma Medium Output Fixed Coil Cartridge

Soundsmith Norma Medium Output Fixed Coil Cartridge

Medium output, otherwise identical to Aida; itself a triumph of Soundsmith Engineering, Stereophile Class “A” rated, a rarity at its price point – and for good reasons. The Aida employs a single crystal Ruby Cantilever and our Optimized Contour Line Contact Stylus; we did this to resolve the challenges of playing the inner grooves with the same level of confidence as the outer. So how did we do this?
