Feliks Audio ECHO 2 Overview


Echo MK II is the entry-level OTL amplifier by Feliks Audio and offers amazing sound
clarity with the typical "tube" feel. The amplifier is fully handmade from high-quality,
carefully selected components. The amplifier's sweet spot lays with medium to high
impedance headphones [from 80ohm) and can be also used as an effective tube pre-amp
for both tube and transistor amplifiers. Ill is built around two 6N1P drivers and two
6N6P power tubes.


Echo is originally equipped with high-quality tubes. Stock tubes are NOS 6N6P and
NOS 6N1 P. Tubes can be changed by the user, to the following:
