EarMen L-Amp MK2 Portable Tube  DAC/Headphone Amplifier

A compact tube headphone amplifier and DAC with NOS JAN6418 vacuum tubes, balanced and single-ended operation, and ESS SABRE decoding up to 32 bit/384 kHz PCM

Tube audio on the go! With its four-point silicone suspended NOS JAN6418 vacuum tubes and onboard DAC, the EarMen L-Amp MK2 is the ultimate statement of classic and contemporary in one stunning unit. 

This limited-edition Miki’s Signature model builds on the first version with a true analog logarithmic potentiometer, refined power-supply control, and improved mechanical isolation for the vacuum tubes.

At the heart of the L-Amp MK2 are NOS JAN6418 vacuum tubes, suspended in a 4-point silicone system to help reduce vibration and mechanical feedback. The circuit is designed to deliver the warmth, texture, and harmonic richness associated with tubes, while offering the control and precision needed for headphones and sensitive IEMs.

The L-Amp MK2 also includes an integrated ESS SABRE DAC section, dual USB-C ports for data and external power, balanced 4.4 mm and single-ended 3.5 mm operation, and Burr-Brown INA1620 SoundPlus™ op-amps. Bass X mode can be activated from the volume control, adding bass dynamics at lower listening levels.
