Espressivo is a single ended OTL headphone and pre amplifier. It in its second generation (as Mark II) was launched in late 2017 and is based on a completely new electric circuit and new tubes: two 6922 driver and two 6N30P power tubes, which brings huge improvement in musicality and details reproduction over its acclaimed predecessor. The amplifier is fully handmade from high quality, carefully selected components and can take 3 selectable audio inputs.
The amplifier’s sweet spot lays with medium to high impedance headphones (from 60ohm) and can be also used as effective tube preamp for both tube and transistor amplifiers. The housing with four beautiful real wood finishes to choose from will match any interior. Same as all other Feliks Audio amplifiers, itis covered by 36 months warranty (12 months for tubes) and free customer service support.
