In Reply to: Why are Japan "First Pressing" CDs considered the best sounding? posted by LoWang on April 13, 2007 at 18:03:15:
I don't know the answer to your question however would you mind posting the links to the sites that sell the CDs. Thanks.

Seems a perfectly reasonable enquiry for this forum.

My understanding is as follows. Perhaps someone closer to the actual business can comment.1- After the mastering of a project, "parts" are made. These parts are then shipped to the plants that actually make the CDs. There are masters and mothers. I believe the mothers are discs in which the pits stick OUT, as these are used to stamp out the copies you buy.
2- The Mothers eventually wear out. Thus, a later pressing of the same CD using the same mother might not be as good.
Somewhere I saw microphotos of CD pits and you could see immediately that it's not as cut and dried as you might expect.
And maybe this is why:
There are 9 different lengths of "pits" and "lands."
You can see at least several of those lengths here.
Here's another resource worthy of your time.
Wouldn't it be interesting to compare the audio on the same (Title) CD from various pressing plants around the world? Some audio magazine, website or club should take this on.
