I never understand this, because different styli require different tracking weight/anti-skate settings. In a relative sense, your own styli, whatever these settings, might be an advantage but it's not the whole story and not completely the answer from my understanding.
I'd be more worried about the dreaded talc Malc ( ).............I would definitley play me raries off CD-R in an environment like that!! Instant sandpaper anyone????
I remember DJ'ing in Bournmouth for top lad Jason Desmond, and when we got there he was taking a couple of boxes out of his bag and promptly changed the styli.........."I'm not asking you guys to come all this way and ruin your records on crap equipment...." he proclaimed. How refreshing! For the reasons outlined at the start of my post, I think it is the promoters responsibility actually.
I agree with Ian, it's nuts..........your tunes ARE there to be played and not just caressed, and you might NOT consider them an investment............but you DO LOVE THEM really don't you??? Just think about it seriously for a moment.
