Know before you buy
Unlike common delta-sigma chips, the Amethyst uses Metrum's proprietary R2R ladder modules. This approach is designed to provide a more natural, analog-like sound signature that excels at revealing subtle textures and precise instrument placement.
The Amethyst is designed to handle a wide range of headphones, supporting impedances down to 16 Ohms. While it is a robust solid-state amplifier, it is best suited for headphones that do not require extreme power to reach their full potential.
Yes, the Amethyst supports high-resolution audio via its USB input, capable of handling sampling rates up to 384kHz. This ensures you can play back high-fidelity digital files with full 24-bit precision.
No, the Amethyst is strictly a DAC and headphone amplifier. It does not include preamplifier functionality or volume-controlled line outputs for external power amplifiers.
Metrum's forward correction technology is an engineering technique used to minimize non-linearity errors inherent in digital-to-analog conversion. It helps the DAC achieve greater accuracy and detail, resulting in a cleaner, more transparent sound.
The Amethyst features a single-ended design and does not provide balanced headphone outputs. It is optimized for standard headphone connections.
