 “The New Sound Reproduction Theory” is innovatively new both theoretically and for practical sound-field-reproduction. "The Extra HI System M" is an achievement based on the theory.

 To measure the sound quality, an objective scale is indispensable. To obtain a true scale to represent what human feel deeply, we have defined an objective scale using the principal components analysis of the whole adjectives.  With the aid of the new measure, we have found necessary physical factors and characteristics for the high-fidelity-reproduction of high definition music playing and artistic media. Obtained factors and characteristics are quite different from traditional requisites.

 Discovered physical factors and characteristics are, the generation of the plane wave, the precise reproduction of precise wave front (waveform), and “High Q”. Realizing those necessities, we are able to obtain “floating atmosphere in the air-like resonance” (n*) and “chest penetrating impression” (n**) and “the overwhelming presence”.

 “The New Sound Reproduction Theory” reproduces a plane wave with less interference wave. It makes a well-projected sound.

Point sound source	2 point sound sources （stereo）	2 point plane wave with a back wall (sound field of our method）

Especially, Extra HI System M Ver. I introduced in the "PRODUCT" page, is evaluated as an “extreme” system as the basic principle components of “floating atmosphere in the air-like resonance” (n*) and “chest penetrating impression” (n**). Another demonstration is “Awesome and cool” and “floating atmosphere in the air-like resonance” (n*) of “Mahler Orch. No1 Chicago Phil., conductor: Georg Solti” by the Extra Hi System ver.III.

Footnotes:
(n*) such as "the sensory and physical impact and sense of awe of been alone a deep forest of a cathedral or performance hall.
(n**) pleasantly tight sensation including sad feeling one gets in the chest to make one’s heart ache when one see or listen something of irresistible appeal.　It includes such a feeling of Japanese state of mind "setsunai". The meaning is "something that gives one’s heart a squeeze though, whether it's those feelings of pain and loneliness one gets when one is in love, feelings of loss, nostalgia and melancholy, or that feeling one gets when one sees a beautiful landscape or painting etc. and there is no equivalent word for it in English.
