Who sets the finishing standard
Kotaro Asahina — recording engineer and microphone designer, and a performing pianist.
He carries on Kaneda-style DC recording, a Japanese school built on direct-coupled signal purity.
He designs and hand-builds the P-86S and X-86S stereo microphones in Japan.
His standard comes from the ear of a musician and the hand of an engineer, in one person.
Free, or Concerto.
Just two plans. No more deciding.
