Optimized for high-impedance headphones (80-600 Ω), it offers a warm, detailed, and airy sound signature. Its design combines a metal chassis with engraved wooden side panels. Tube rolling compatible, it includes three RCA inputs and a preamp output.
A Tube Legacy at the Service of Music
In the world of tube amplification, Feliks Audio has established itself as a reference alongside renowned names like Cayin. The Echo Vibe represents the new generation from the Polish brand: a compact model that blends traditional craftsmanship with a modern, engaging sonic signature.
Finish and Design
The Echo Vibe immediately captivates with its elegant design. The metal chassis is enhanced by engraved wooden side panels, adding a precious artisanal touch. The whole unit exudes high-end quality, with noble materials and exemplary build.
Note: The power switch located at the rear is not easily accessible, and the amplifier can be sensitive to electromagnetic interference (keep it away from wireless devices).

Sound Quality

Performance According to Impedance
-
Low-impedance headphones (Meze 105 AER, Meze 99 Classics): clean and textured bass but lacking physical weight. The signature remains pleasant and musical.
-
High-impedance headphones (T+A Solitaire P wired): radical transformation – consistent and impactful bass, denser mids, captivating vocals. This pairing reveals the amplifier's full potential.
The treble, always refined and non-fatiguing, carefully avoids any aggression. The soundstage, wide and airy, places instruments with a certain distance, favoring space over frontal intimacy.
Strengths and Considerations
| Strengths | Considerations |
|---|---|
| High-end construction (wood, metal) | Rear power switch impractical |
| Quality NOS tubes | Sensitivity to interference |
| Warm and detailed sound signature | Limited power for very low impedance |
| Tube rolling compatibility | |
| Excellent soundstage with high-impedance headphones | |
| Remarkable pairing with T+A Solitaire P |
Verdict
The Echo Vibe is an amplifier with character that truly thrives with high-impedance headphones like the T+A Solitaire P wired. With them, it delivers expressive, natural, and enveloping music. More reserved with low-impedance models (Meze 105 AER, Meze 99 Classics), it remains nonetheless musical and enjoyable. An exceptional piece for purists seeking an authentic tube signature.
