How do you spot an overplayed used lp without obvious scratches etc


I'm pretty good at spotting record defects and scratches that will or won't affect sound quality.
Even with a well done cleaning, you play what looks like a good album and it has simbilence, a rough thick surface noise etc.

how do you spot these from a gem pressing?,

The 1980 Japanese Trick of the Tail is very nice


I track at 1.8 on my ZYX Universe

I considered a second arm with a less nuanced cartridge for heavier rocking stuff



audiotomb, 

1.8 should it very good.  Honestly, try the conical stylus first.  I don't use it all the time, but it's so good sounding I really might soon.
