Highest quality vinyl I have is Japanese from seventies and it's not 180g. I think, these thick and heavy records are a complete waist of the resources, you also have to adjust the tonearm each time you play them. In addition, I tried couple of 180g reissues, and I don't know whether it was remastering or the weight and thickness of the records or both, but I didn't really like what I heard, it felt kind of 'stupid'. Maybe my Spacedeck just doesn't like them, yeah maybe, I am quite certain it was not voiced and tuned using them. Anyway, just give me older Japanese quality regular weight vinyl and I'll be happy.
