Soundsmith Sussurro MK II Moving Iron Cartridge
Description
The Sussurro ~ critical design decisions, realized. Lowest internal mass. Best damping. Esoteric stylus and cantilever. If you need to stay in constant contact, your cartridge has arrived.
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.
New ES Series DEMS design :
What is DEMS??
“Sometimes you can judge a book by its cover.” – Peter Ledermann.
2018’s RMAF show was the official launch of Soundsmith’s new ES series of cartridges, where the attendees experienced the latest exploration into overlooked areas of cartridge design and solutions from Soundsmith.
The ES line features not only a dramatic new look, but is a significant evolution of the DEMS system design (Dynamic Energy Management System). The new Soundsmith ES cartridge designs are a significant advancement in cartridge performance due to their ability to direct internal vibrational forces without reflection and disperse them properly to the tone arm. The absence of reflections enables the stylus to stay in far greater statistical contact with the groove walls — a critically important technical refinement. Increased liquidity and reduced “grain,” without loss of detail are some of the immediately discernible advantages of Soundsmith’s new ES models.
The new line also features Azimuth adjustment built-in to each cartridge, as well as the option for electrical isolation for hum-prone systems. (see picture below)
Every cartridge in Soundsmith’s lineup will now feature our sleek new ES body design. The upgrade is far more than cosmetic; the new shape is a departure from the reflective and “boxy” design of many cartridges whose internal construction contribute to uncontrolled vibrational issues adversely affecting performance. Peter says, “Think of how singing in an open field compares with singing in a shower.” Soundsmith has always challenged conventions, looking deeper into nuances of cartridge design that dramatically affect immediate and long term performance. These have included extreme reductions of moving mass and the use of novel materials and designs. The new ES lineup is a continuation of that research and development.
