I have seen this term around, but I don't know exactly what it means. I suppose it has something to do with the mass of the actual record itself, or was somehow derived from some such historical meaning. I have seen references such as "180 G Audiophile Vinyl". I also saw a listing for 120, 150 and 200 G vinyl, among other things. Have a look
here for the different vinyl categories.
I Googled and Wiki'd, but didn't find much (I didn't really look all that hard, and thought it might be worthwhile to have such a thread here).
So what's up? What's the good stuff? And the junk to avoid? And really, what are the differences between these differently categorized records?
