Feliks Audio Envy Susvara Edition

9-Watt Class-A 300B headphone amplifier with amorphous output transformers

Power and authority for the most demanding headphones

The Envy Susvara Edition is the most powerful evolution of the acclaimed Envy platform. Delivering up to 9 watts of pure Class-A power, it was engineered for extremely demanding headphones such as the HIFIMAN Susvara.

Three gain settings (“Low”, “High”, “Susvara”) ensure optimal matching. The dedicated Susvara mode provides up to 12% more output compared to the original Performance version.

Amorphous transformers & selected 300B tubes

Custom-built amorphous-core output transformers ensure ultra-low noise, superior dynamics, and extended frequency response.

The amplifier comes equipped with carefully selected Stradi S300B power tubes and PsVane CV-181 Mk2 drivers, delivering precision, air, and exceptional technical resolution.

Reference-grade components

Signal-critical components from Jantzen, Vishay, Nichicon, and Dale, along with optimized internal wiring and improved interference management, elevate the Susvara Edition close to Anniversary Edition standards.

Handcrafted in Poland with a solid wood chassis (standard: Wenge), the Envy Susvara Edition represents uncompromising endgame engineering.
