Smooth, natural and engaging

At its core, the Echo Classic delivers the same lush and organic sound reproduction that has made the Echo family a bestseller. The sound is rich yet balanced, with a touch of warmth that highlights vocals and instruments without sacrificing clarity or resolution. The bass gains fullness and texture, the midrange sounds open and nuanced, and the highs retain their sweetness and airiness – smooth and never harsh.

This makes the Echo Classic the ideal partner for long listening sessions where musicality and natural timbre are more important than sterile precision. The design suits a wide range of headphones, especially those in the 80 to 600 ohm range, from dynamic classics to more demanding audiophile models.

Crafted with care

Like all Feliks Audio amplifiers, the Echo Classic is handcrafted in Poland with a focus on durability, performance, and timeless aesthetics. By simplifying the construction and omitting additional features such as pre-amp outputs, Feliks has made the Echo more accessible than ever – without compromising the sonic core that defines its character.
