EarMen ST-Amp

Desktop Fully Balanced DAC / Headphone Amp / Preamp


Experience exceptional audio quality with the EarMen ST-Amp, a fully balanced desktop headphone amplifier that also doubles as a preamp with an integrated DAC. Our device is meticulously crafted to provide extraordinary sound, whether you're using the integrated DAC or an external source, making it the perfect all-in-one solution for discerning audio enthusiasts. Say goodbye to unpleasant "Pop and Click" phenomena when powering on or off your amplifier, as we have carefully engineered our design to ensure a seamless user experience.

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.

Captivating Dynamics

Prepare to be captivated by the EarMen ST-Amp's incredible dynamics. 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. Experience perfectly balanced sound reproduction that leaves no room for missing out on any auditory intricacies.


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.

Uncompromising Audio Fidelity

We understand the importance of low Total Harmonic Distortion, and we take it seriously. The ST-Amp boasts exceptionally low THD, allowing for a higher power factor, lower peak currents, and increased efficiency without sacrificing audio quality. Immerse yourself in pristine, distortion-free sound reproduction.

Robust Power Supply

At the heart of the EarMen ST-Amp lies a noiseless linear power supply with outstanding stability. This power supply effortlessly delivers ample power, even for the most demanding headphones.
