Soundsmith Helios Medium Output Phono Cartridge
Our new medium output design, the Helios is otherwise technically identical to the Hyperion. The Hyperion is the cartridge of choice for the most esteemed audio equipment manufacturers. Why? Because when they exhibit their gear at Hi-Fi shows, they want their turntable, amplifier or speaker systems to sound the very best that they can! Peter Ledermann‘s radical design utilizes an actual “cactus spine” for the cantilever. The naturally tapered shape, stacked columnar fibers and desiccated resin damping fit the exact parameters of the perfect cantilever: Low mass, extreme rigidity, internal damping, and tremendous strength.
