What Vinyl quality should I be using?

Not true! I have many "standard" LP's that sound much better than 180 or 200gm reissues. I hate it when people make sweeping statements like that. The quality of sound has more to do with proper recording than whether it is on "Audiophile" vinyl.

So you are willing to only play certain vinyl.....what a sad little life that would be! I hope who ever told you this isnt your boss because it would be difficult to work for an idiot :)

The problem is that many of the best musical performances don't give you a choice as to format and quality. I know I'm not giving up the music I love just because some fancy "audiophile" version isn't available.

Further, ordinary music will not damage a high end system as long as the pressing is in presentable condition. Any system that is so delicate that it cannot play an ordinary recording isn't worth having.
