Opera Consonance M10 Tube Integrated Amp with Headphone Jack

Opera M10S Tube Integrated Amp in excellent confition. Uses both KT88 and EL34 output tubes and includes an outstanding headphone jack. I am the original owner. It is just under 2 years old. Stock EL34 tubes will be included although KT88 are in the picture.

M10S is a single ended Class A tube integrated amplifier - in stock
form it comes with EL34 power tubes - bias preset at factory with test
spot inside the chassis. 

Like many other Consonance tube amps, this amp provides you with refined sound along with top quality workmanship. 

This is a compact sized amp to perfectly fit an office or a small
listening room without taking up much footprint. You get the classical
Consonance sound but do not have to do much heavy lifting :)
