So I just inherited a bunch of CD's and some are made overseas...

I have multiple CD issues of the same artist from the US, West Germany, EU, and Japan. These are original flat pressings, not remasters.
There may be differences in dynamics, high and low-end extension, soundstage, 3D imaging, and noise-floor resulting in more separation between instruments. Early issues may sound different than later issues and there’s no guarantee that a first pressing has better SQ than a later release.

Typically I like the SQ of German releases (later issues are labelled as EU). And I’ve found that Japanese pressings are consistently of very high quality.
    Of course, you must have a high quality CD setup to reveal these differences.

Other than the liner notes which are in a foreign language, is there any difference between them sonically?  

Listen to them and decide for yourself.

Thanks elizabeth for the link.  I do have some WEA disks, but none with the bullseye logo on them.

I'll keep looking though.

Also keep in mind that the "Made in Xxxxxx" has no bearing whatsoever
on where the record company is that released it.  US record companies would use whatever CD plant gave them the best deal on replication.  The sound quality has everything to do with the digital MASTER that was supplied by the record company.  Many US releases back in the 80's & 90's were Made in Germany, because they had a lot of CD pressing plants.  
Now.... if the printing is in German or Japanese... then clearly it's a foreign release... but who knows where the digital Master came from. I've heard them be bit-for-bit copies of the US release, but i've also heard some sound really bad.  You just don't know until you hear it and compare.
