Recent vinyl returnee. I have vinyl from the 70s mostly (bought then) and some from the 80s.I dont get the whole 180g or 200g re-release thing. What is the point? If you are using a good turntable mat like a hexmat eclipse and a turntable clamp or weight what does it matter? What does a heavier record do? Is all my vinyl from the 70s crap? Doesnt seem like it?
