ECHO VIBE
OTL Vacuum Tube Headphone Amplifier
Feliks Audio's best seller, now upgraded on the inside and out to be better than ever.
Echo Vibe refines its predecessors' classic soulful character of OTL tube amplification. Upgraded capacitors improve high-frequency detail, and a reworked transformer with improved shielding reduces interference and enables even quieter operation. Three sets of RCA inputs and mute functionality ensures convenient use.
Echo Vibe offers amazing sound clarity and musicality with a typical "tube" feel. The amplifier is fully handmade from high quality, carefully selected components. Built around two 6N1P driver and two 6N6P power tubes, it can be also used as effective tube pre-amp for both tube and solid state power amplifiers.
The refined design is hand crafted in Poland with real metal, new precision CNC engraved wood side panelling, and for the first time, integrated wooden feet.

The System
Echo Vibe is built with 2x 6N6P and 2x 6N1P tubes. Its power supply is based on a custom-made stabilized toroidal transformer with electronic ripple suppression. Upgraded capacitors within, new to Echo Vibe, unlock greater high-frequency detail reproduction and livelier dynamics. The amplifier is equipped with automatic bias circuit, therefore no re-tuning is required after changing tubes. Its sweet spot typically lays with medium to high impedance headphones, from 80ohm and up.
Enhanced Design
Echo Vibe boasts a beautiful new design, featuring an upgraded transformer housing that not only looks sleek but also enhances interference resistance. The refined wood panels, now with precision CNC engravings and integrated wooden stands, add a touch of elegance.
OTL
'OTL' refers to a tube amplifier that is Output Transformerless. Echo Vibe offers a highly musical and detailed sound that is true to the tubes themselves by omitting output transformers, which can colour the sound. Feliks Audio has always followed design simplicity, minimizing the number of elements in projected signal path; thanks to this approach, we ensure that the sound produced by our devices is pure and true.
