Differential signaling at low sound levels.

Given that radiation (commonly related to solid state) affects both solid state and cartridge cables, differential signaling is designed to target any interference. Potential ground noise issues are resolved and solid earth ground wiring is no longer required.

HD vinyl digitizing.

Expert Pro also features an intelligent vinyl digitizing system thanks to adjustable digital sampling rate output (up to 192 kHz/24 bits).

Bridging the divide between analog and digital-era technologies, RAM® seamlessly adapts your Expert Pro phono stage to fit any vinyl recording. Meanwhile, ADH® intelligence delivers perfectly transparent amplification and SAM® tailors the sound signal to your exact speaker specs: a radically superior triple parallel action that lets you reach new extremes, making Expert Pro the class leader in audiophile solutions.
