We have confirmed the fact that the sound quality of copied digital signal is, in some cases, better than the sound quality of the original CD", then we have considered the concerned factors and characteristics to improve the sound quality. Since no sound quality measurement tool exist, discovered two objective key perceptual assessment phrases of <B>losing "floating atmosphere in the air-like resonance"</B> and <B>losing "chest penetrating impression"</B> (Appendix 1) are used for the evaluation of the sound quality. The improvement of sound quality is up to +3 in the 7-grade comparison scale.
