  2. Data sheet

Audio Opera is a Chinese company. Who is M 100 plus from the consonance series but before the amplifier, never would and never smell a Chinese product. What is so “dangerous” audio Opera: this company not copied European or American tube amps to the known schema, but developed itself from the circuit to the design. If necessary the “WBT-like” speaker terminals on the back show that audio has still role models Opera let by an elegant ‘new interpretation’ bought into Chinese.

The message of this amplifier: “handsome”. A massive trio of transformer and two transmitters is surrounded by massive wooden cheeks–before four EL34 tubes from formerly Soviet Communist brother country glow. The feeling when flipping the on/off toggle switch is exquisite. This tube feeds the speaker not just with the cliché of tender, warm Glimm sound. As Curative, the 100 M can provide 40 watts per channel – some transistor, however, looks like a softie. Also, the switching speed is designed. The basses have real pressure, the “Punch” is there. On top of that dynamic, which can organize large orchestral music.

What the real tubes fans will always love: between the power fields of deep bass and lower midrange M 100 conjures up a deliciously round upper bass – each musical event is built around. If there is a catch: just the beautiful wealth can shrink the CinemaScope effect depending on the music material – the soundstage appears more closely, but also direct. More a matter of taste as a real drawback.
