Overview
Choose your power...
The award-winning WA7 Fireflies is now also available for electrostatic headphones. At the heart of the WA7e is a fully-balanced amplifier designed for modern electrostatic headphones from Audeze, STAX, HiFiMan, Dan Clark Audio, and others.
Thanks to the unmistakable elegant look and compact design, WA7e stands out from conventional electrostatic headphone amplifiers. To fit all of the features that users expect and love to use, our engineers developed a complex internal structure with specifically designed custom-made components. The ESS SABRE DAC you know and love makes your music sound incredible and the user-replaceable 12AU7 vacuum tubes can be upgraded at any time to customize the sound to your preference. The built-in linear power supply simplifies system setup and location versatility. The WA7e is also a tube preamplifier allowing you to integrate with home speaker systems or drive a pair of desktop-powered speakers for more ways to enjoy uncompromised sound.
Whether you choose WA7 or WA7e for your headphones collection, great sound runs in the family.
