Starting a classical library is BMG an answer?

The choice about BMG is a matter of opinion, listen for yourself and decide. Personally I do not buy BMG.
I chose do stick for the most part with major labels. Get a copy of the Penguin Guide and read some reviews before you buy, Grammaphone magazine is also good. I beleive the reviews are important. I also look at who is preforming and conducting and there are certain ones I like and dislike. I have also found that I sometimes sacrifice a bit of recording quality to get a better preformance.

In reading these responses I see that many here do not feel there is a difference in the recorded quality of cd's from various facilities.
One of the reasons I differ in this opinion is reading another thread talking about Japanese cd's and the overwhelming response was that people said that the Japansese cd's sounded better. Why is this the case?
