Gold disk VS regular disk?

Hi,
Thanks for all your helps. I asked this question because there are several albums that I like have both Gold and Silver. However, the Gold is double the price comparing to Silver disk. Well, I decided to buy the Silver disks.
Thanks again

I agree that remastering is the main source of any improvements. As long as the laser decodes both aluminum and gold disks correctly then there will be no difference in sound. Is gold more reliable then aluminum? Maybe a CD transport designer will weigh in with an opinion.

I believe Mobile's claim was that gold is more malleable, reulting in better pits which can be read more accurately, therefore requiring less correction aka distortion.

With regard to earlier and later version of the same album, if they were manufactured in the US, early US plants had a terrible process quality problem. The yield of acceptables was very low and it took a long time for some plants to even come on line. Perhaps a lot of the earlier discs, although deemed acceptable, still had "bad pits" and required a lot of correction.
