Echo Mk II


    • The Echo is an output transformer-less (OTL) headphone amplifier and preamplifier featuring  6N6P and 6N1P tubes. Despite being Feliks’ entry-level amplifier, the Echo is no slouch when it comes to presenting a highly musical and well-extended sound. The Echo is slightly warm, smooth, intimate, and laid-back, flattering a wide range of headphones.

      These qualities, in addition to incredible build quality and brilliant engineering, amount to an amplifier that performs far beyond its class. It is fully handmade and the headphone sweet spot is for medium to high impedance headphones (from 100 ohms). It can also be used as a tube preamp for both tube and solid-state amplifiers.
