The sound at the time of beginning to appear of CD was bad in old times.
CD to say that the noise was small and was swinging. The lower bound was cut with Sresshuhorld of the noise reduction and CD Preyar like the thing etc. to raise the one high pitched sound was also the worst.
 

 

Recent CD can considerably hear, and thinks the neighborhood to an old analog record where the performance noise (noise that touches atmosphere and musical instruments where the people exist) is heard because the noise etc. are excessively cut and it doesn't exist. The air feeling goes along somewhat, too.

The reproduction ability in the bass region of CD is wonderful. However, the upper register is bad. There is a reason why CD is said that the high pitched sound is beautiful. Please give mail to the person who understands the reason.

My ear is made to become, too and it has worsened.
