DAC ---- can it improve cheap cheap CDP ??!!

avlam

威馬兄已經講出重點了，唔係單單講緊jitter，我自己覺得要留意的是20KHz高頻滾落的問題。
由於規格上16/ ...

    呢d又係關於Program算法既質素，同埋High-Cut 個位搞得好唔好了

你吾講我真係吾知呀!  
如果套野jitter 控制得好係吾係升吾升都無咩所謂呢？
另外如果先用audi ...

basically yes, but async upsampling is the cheapest way to reduce jitter, othe real effective way of de-jitter othen then async upsampling, mostly only could see in CDP up to at least $80K - $100K.

upsampling the file is not the same, hardware async upsampling inside CDP or DAC is related to clock.

升頻從來都唔係用來補救或增加細節，升頻係利用異步方式減低 JITTER 同 LPF 部份唔洗響 20KHz 一刀斬，容 ...

可能會有少少改善但未必明顯，也要留意升頻不一定好聲D。

上次個sales 吹加咗DAC, 用普通BDP play CD 都可以接近萬元CDP 質素......
