Unparalleled Balanced Performance

Our amplifier boasts full balanced functionality, delivering cleaner and enhanced sound reproduction from your input. But that's not all - we've employed the same top-notch topology for single-ended (SE) signals, resulting in a unique balanced output with minimal phase shift, additional noise, or Total Harmonic Distortion (THD). This means the sound from the SE output is on par with the performance of the balanced output

Unrivaled Audio Prowess

With the EarMen ST-Amp, your DAC's capabilities will shine brighter than ever before. While many DACs offer impressive specifications, they often fall short in fully expressing the audio's true potential. Our ST-Amp optimally utilizes the maximum dynamics provided by the sound source, ensuring that no detail is lost. Additionally, it effortlessly drives various headphone drivers, enhancing accuracy, neutrality, and transparency.

With a dynamic range exceeding >126dB, our device imbues your music with liveliness and musicality, transporting you to the exhilarating ambiance of a concert hall.

Versatile Preamp Functionality

Equipped with SE and BAL Pre-Out outputs on the rear panel, the ST-Amp doubles as a DAC and preamplifier, seamlessly integrating into more powerful audio setups. Enjoy the flexibility of choosing your preferred sound source, whether it's an analog input or a digital/integrated DAC. The choice is yours, and the EarMen ST-Amp adapts to your audio preferences.
