SPL Auditor Headphone Amplifier

The Auditor is our interpretation of a high-end headphone amplifier. We strictly followed a purist approach to achieve the highest sound quality. Based on our 120V rail reference technology. Auditor reaches performance levels far beyond conventional designs in dynamic range, slew rate, noise and distortion levels. Alps well acclaimed Big Blue volume potentiometer complements the design philosophy.

Features

• We strictly followed a purist approach to achieve the highest sound quality.
• The basis for such high-end developments is our 120 V rail reference technology.
• Core elements are the handmade SPL SUPRA op-amps running on 120 volts – it corresponds to approximately twice that of most modern analog audio semiconductor technologies.
• Through such 120 volts circuitry and processing we reach performance levels far beyond conventional designs in dynamic range and distortion levels, and such technical specifications exceed all known analog or digital standards.
