跟住 RIP 左一首歌四次（每部機梅花間竹咁 RIP 左兩次）：

師兄, 有心機. 唔知聽起上來感覺有咩分別?

我只可以講，從 HASHCODE 上睇，兩個 DRIVE RIP 出嚟嘅 FILE 係有分別嘅，但邊個更接近／等於原來隻 CD 想 STORE 嘅 DATA，無人知。而且，兩者唔同究竟會否因為EAC 儲起 DRIVE SPECIFIC INFORMATION 於 WAV 內的 METADATA 中？根據 WIKI：
http://en.wikipedia.org/wiki/WAV#Metadata
“WAV files can be tagged with metadata in the INFO chunk.”
所以“有可能” EAC 放左 DRIVE INFORMATION 落 WAV 度，只係我唔識點 PROVE...

個人其實唔係好發燒，只係好奇下做呢個實驗，我無做聆聽實驗，因為無論結果如何，（如上文提及）實驗都係 BASE ON 好多 UNCERTAINTY 上進行，即係只係主觀見解。（我覺得先起碼要 PROVE 兩個 FILE 內的 METADATA 係一樣，對不對？）

我都希望有識之士能夠作更近一步的科學化驗証。

0岩0岩試過用呢個program去比較一隻lenovo usb dvdrw drive 同另一隻plextor usb blu-ray drive. 發覺係一樣. 可能隻plextor轉0左made in china都係麻麻地.

隻plextor唯一比較好就係唔熱, 對cd傷害比較少.

Am under the impression that it won't. Metadata for WAV, while technically a standard (inherited from RIFF), isn't implemented in most software -- not only that, poor implementation of metadata for WAV files tend to break the containers...

Anyways, I believe that the WAV files EAC generates are metadata-free...

Yes, I agree with you. That's why I believe that my two drives generates two different versions of WAV files. The question is, which one is more precise...
