好像是在說High End音響中，非傳統名詞可以解釋的失真現象，就歸在 P.E. (Phoenix Effect) Distortion

規格一樣的線材，擴大機，聽起來不一樣
黑膠、MP3在某些系統中聽起來比高解析格式好
熟化後聲音不同
規格很漂亮，聽起來不好聽
管機系統....

例如
• One cable sounds (looks) different than another, even when most known electrical values seem
similar and don't apparently support the differences.
• One amplifier sounds different than another with almost identical specifications.
• Why vinyl record, playback and even MP3 can in some systems sound better than a high
resolution format.
• How systems can sound different after a break in period.
• An amplifier with exceptionally low conventional distortion levels can sound "veiled" or have
poor sound stage depth.
• Tube electronics may have a countering effect for P. E. Distortion elsewhere in the system.
