Soundsmith Sussurro Moving Iron Cartridge MKII

Inspired by Frank Schröder, designed and individually hand made by Peter Ledermann, Soundsmith's Sussurro is a cartridge designed to specifically address the most intricate and critical issues of cartridge design. The new MKII Sussurro has a newly designed moving iron element to reduce moving mass by 70%; extremely low stored energy, the new MKII damping system and an innovative energy distribution path to effectively transfer mechanical energy away from the cantilever through the cartridge body into the tone arm. So what does all this mean??

Low jitter. Jitter? You probably thought that was a term reserved for digital systems. Not so. Stylus jitter is responsible for loss of detail, and making a cartridge sound, well, like a cartridge. The Sussurro stays in constant contact with the record groove. If you are not in constant contact, you can't hear what has truly been recorded.
