Technical data is just an improve that item was tested carefully before sending to customer. While our products consistently achieve good to excellent technical figures compared to commercial alternatives, those numbers serve only to confirm that the design contains no engineering errors.
We could, in most cases, apply active techniques to make the specifications look even more impressive — but if doing so strips away originality or musical character, we will not do it. Our aim is to build equipment that sounds beautiful, not equipment that measures beautifully.
At OTOMON, music is judged by the ear and no instrument can replicate the human 's ear.
