Description
The Feliks Audio Echo Vibe is the successor to the Echo MKII, bringing a refreshed design and upgraded internal components to one of Feliks Audio’s most approachable tube amplifiers. Handcrafted in Poland, Echo Vibe is built for listeners who want classic OTL tube character with the clarity, low noise floor, and desktop-friendly usability needed for modern headphone listening.
With its 6N6P and 6N1P tube configuration, 350mW of output power, and 20dB of gain, Echo Vibe is an ideal match for high-impedance headphones from 80Ω to 600Ω. The sound is warm, dimensional, and naturally textured, with rich midrange body, smooth treble, and an open sense of space that makes it easy to understand why tube amplification remains so addictive.
Classic Tube Warmth, Modern Feliks Refinement
Echo Vibe keeps the spirit of the Echo series intact: an inviting OTL tube amplifier that brings music closer without making the setup feel complicated. It delivers the glowing midrange, natural decay, and spacious presentation that tube lovers chase, while maintaining excellent detail retrieval and very low noise levels for a cleaner listening experience.
The updated internal layout and upgraded capacitors give the Echo Vibe a more dynamic and lively presentation than the model it replaces. Transients feel more vivid, high frequencies have better energy and expression, and the overall sound keeps its warmth without becoming overly soft or slow.
Successor to the Echo MKII
The Echo Vibe is more than a visual refresh of the Echo MKII. Feliks Audio updated the amplifier’s design, shielding, capacitor layout, and chassis details to create a cleaner, more polished version of its entry-level premium tube amp. The new transformer housing improves resistance to interference, helping keep background noise low and the presentation focused.
The exterior has been refined as well, with updated walnut side panels, precision CNC engraving, and integrated wooden stands. It still has the handcrafted charm Feliks Audio is known for, but the Vibe feels more finished, more elegant, and better aligned with the rest of the Feliks lineup.
Built for High-Impedance Headphones
As an OTL tube amplifier, the Echo Vibe is best suited to high-impedance headphones. Pair it with dynamic-driver headphones in the 80Ω to 600Ω range and it rewards you with the qualities that make tubes special: depth, tone, body, and a more natural sense of space around instruments and vocals.
This is the kind of amplifier that works beautifully for long listening sessions. It adds warmth and dimensionality without burying detail, making it a strong choice for listeners who want a more organic and emotionally engaging presentation from headphones that benefit from voltage swing and tube-driven texture.
Practical Tube Amplification
Echo Vibe is designed to make tube ownership feel easy. Its automatic bias circuit means there is no need to manually re-bias tubes, while built-in input and output safeguards help eliminate power on and power off noise. Feliks Audio also includes a preamp safe mode, giving the Echo Vibe more flexibility in a desktop system.
With three RCA inputs, one RCA line output, and a 6.3mm headphone output, Echo Vibe can serve as the heart of a dedicated headphone setup or as a tube preamp in a compact two-channel chain. It brings the feel of a traditional tube amp into a cleaner and more convenient form.
