Here is official page of OTOMON LAB, you can check the newest arrival product or contact us I have told you about the meaning of our name.

Here is official page of OTOMON LAB, you can check the newest arrival product or contact us here. Today I will tell you about our logo. The word "音" in the center of logo is OTO means the sound. The Miazima symbol is same as word "門" (MON) means the gate. It is nealy same "N" symbol in English. The red circle is same as "O" character, it combine with the red M character to become "MON". S

o, in the logo we have OTOMON ! By the way, in Japanese, as you put the word "OTO" into the word "MON", it becomes the word "闇", you can spell it "YAMI", mean the dark, same as hell. In the mean time, the red symbol in the center of logo have symbol like a sun, the bright side, the heaven. The word "mon" in Japanese means the gate, and also it means the bondary separates 2 worlds, in this logo it means the border line between the heven and hell and "the sound" is in the heaven side. It is same as symbol leading us thinking about the image of phantom in the Opera, the music in heaven and the dark side without it. That is reason why the background color of our website is black. The "M" word is also the symbol of mountain, the image of red sun raises up on the top of Fuji mountain is always the best symbol of Japan. Thank you for reading.

71A/205D tube preamp with Otomon Finemet Attenuator Transformer 36 steps.

Hum level : 0.05mV, response frequency 10Hz~70KHz
--------------------------
Our objective is not to chase arbitrary bench measurements for the sake of specifications alone, even though our amplifier comfortably outperforms most standard products on the market. While we possess the engineering capability to force even lower distortion figures on paper, we deliberately choose a different path.

Our true focus is the emotional energy and vitality that music conveys, which can not be calculated by any machine, rather than achieving the lower possible THD or the wider frequency response. To capture the true soul of the music, we willingly accept trade-offs in conventional technical data when it serves the ultimate listening experience.
