“It looks like it was designed to sit on a smart person’s desk, beckoning constantly to be used. With every headphone I tried, it performed as though it had been engineered to present recordings in the most vivid manner possible, be 100% musically satisfying, and be the last headphone amplifier any of us might need to own. “

“It’s always fun reviewing high end gear. The Feliks Audio Envy 300B tube amplifier is among the best on the market. It’s a truly high-end amplifier with an incredible sound. It costs a pretty penny but if you have the budget you will never ever need a different tube headphone amp.

The Feliks Audio Envy is a future classic already. If you have the chance listen to it, you absolutely should. And sorry about your wallet, because you’ll want one once you’ve heard what it is capable off.”
