Highlights

• Entry-level tube amplifier – pure sound, no extras, no frills
• Smooth, organic tonality – rich mids, textured bass, sweet treble
• Hand-crafted in Poland – premium build quality at an accessible price
• Optimized for headphones from 80–600 ohm

Smooth, Natural, and Engaging

At its heart, the Echo Classic delivers the same lush and organic presentation that has made the Echo family a bestseller. The sound is rich yet balanced, with a touch of warmth that enhances vocals and instruments without sacrificing clarity or resolution. Bass gains body and texture, the midrange feels open and nuanced, and the treble retains sweetness and air – smooth, never harsh.

This makes the Echo Classic an ideal partner for long listening sessions, where musicality and natural timbre matter more than sterile precision. It’s a design that complements a wide range of headphones, particularly those in the 80–600 ohmrange, from dynamic classics to more demanding audiophile models.

Crafted with Care

Like every Feliks Audio amplifier, the Echo Classic is built by hand in Poland with a focus on durability, performance, and timeless aesthetics. By simplifying the construction and removing additional features such as preamp outputs, Feliks has made the Echo more accessible than ever – without compromising on the sonic core that defines its character.
