The purpose of this paper is to call attention to the
changes in audible and measurable performance
that occurs to any DAC over a 24-hour period. Listening
to a cold digital device (any DAC that has been
unplugged for one hour or more) will significantly
shortchange the experience and negatively impact
the desired outcome. However, a 24-hour warm-up
period can – and most often will – significantly
improve DAC performance. Moreover, comparisons
between a suitably warm DAC and one that is cold
can result in invalid findings.
大意:解码在暖机24小时后,才能发挥最佳效能(更低的相位噪声)。
所以你们AB器材,或者换线,或者今天觉得好听第二天觉得不好听的时候,会不会是因为这个原因?暖机时长不够。
如果听完就关掉解码,那么下次听的时候,它可能都没真正暖起来。
