Comments and Reviews
Overview
With over 10 years of experience in electrostatic amplifier designs. The all-new 3ES is our flagship electrostatic headphone amplifier and preamplifier. It shares the same architecture as our flagship WA33 dynamic headphone amplifier in a two-unit design where the top unit is an amplifier docking on the power supply using our internal coupling architecture (ICA) technology. The 3ES employs two 6SN7 driver tubes pushing four 300B power tubes as the output stage and one rectifier tube in the center of the amp. The new 3ES achieves the most ambitious dream in the audio world.
