The EarMen L-Amp Brings the Power and Quality of a Desktop DAC/Amp to the Palm of Your Hand, Featuring NOS Vacuum Tubes for Rich Sound Portable high-fidelity DAC/Amp Features Raytheon JAN6418 electronic vacuum tubes Integrated ESS Sabre DAC ensures flawless audio reproduction Experience the warmth of vintage tubes with modern-day precision Includes SE and Balanced outputs Rediscover Audio The EarMen L-Amp is the perfect marriage of vintage charm and modern engineering. With electronic vacuum tubes (JAN6418) and a powerful 1W at 8Ω output, the L-Amp redefines portable audio. It offers the iconic tube signature sound beloved by audiophiles while incorporating cutting-edge technology to deliver precision and clarity. Whether you’re seeking a desktop-grade audio experience or a portable companion, the L-Amp has you covered. JAN6418 Vacuum Tubes The L-Amp features Raytheon JAN6418 directly heated vacuum tubes, valued for their compact size, low power use, and reliability. Unlike typical portable devices with 5V or 12V power supplies, it uses a 22.5V anode power supply, ensuring superior headroom and optimal tube performance. Made in the USA, the NOS (new old stock) vacuum tubes provide a warm, rich and natural sound signature. The innovative suspension system featured in the L-Amp drastically reduces vibration using 4 silicone O-ring mounts. This system minimizes mechanical feedback to ensure clarity and consistency in every note. Powerful Performance The power stage of the L-Amp is built using Burr-Brown® operational amplifiers INA1620, renowned for their ultra-low THD+N, exceptional performance, and SoundPlus™ technology, ensuring superior audio quality and reliability. The fully balanced circuit found in the L-Amp seamlessly operates in SE and Balanced modes with no additional adjustments required. 1W at 8Ω output power handles everything from low-impedance IEMs to high-demand dynamic headphones. Additional Features Advanced DAC TechnologyIntegrated ESS SABRE DAC (32-bit, 384kHz PCM, DSD DoP128) ensures flawless audio reproduction, whether you’re on the go or using it in your desktop setup. IEM ModeThe EarMen L-Amp features IEM Mode: dedicated circuitry for optimal performance with in-ear monitors Versatile ConnectivityThe L-Amp includes dual USB-C ports, one for data and one for external power supply, preserving your phone or device battery life. Additionally, the DAC/amp is compatible with USB power banks or external chargers for uninterrupted playback.
