Our phono stage circuitry uses only the best audiophile components. Computer matched op-amps, high-gain bi-polar output transistors to Nichicon audio-grade capacitors. And much more. With a stunning, super-low 85dB noise floor (per Stereophile standard) the iPhono3 Black Label is out there. One of the quietest phono stages. Period. Like any good phono stage, it amplifies the signal, not the noise. The whisper-quiet noise floor is there for any home audio system to discern. Take it for a test drive from the comfort of your favourite listening chair. Precise EQ curve and explosive 108dB dynamic range.
