How Much Surface Noise is Too Much?


Just curious as to a range of opinions here. At what point is an LP unworthy of being played with your stylus/cartridge? Should one expect a used record store to give refunds on LPs which turn out to have more than a certain amount of surface noise/warpage and, if so, how much damage/defect should be criteria for getting one's money back? Any other thoughts along this line?

I'll put up with more noise if the record is a hard one to find or if the underlying sound is especially good but Tvad is right, everyone's tolerance differs. Digital sensitized many to this more I think. The longer you play vinyl, the less a little noise seems to bother.
I'm surmising that styli/cartridges are pretty tough versus most run-of-the-mill record surface issues from an old brochure on the Linn LP-12 I remember reading ages and ages ago which said something to the effect of "even your battle scarred old discs will take on a new life...", but is there a point at which most of you reject the idea of playing a record out of fear of damaging equipment? How bad does a scratch have to be from this standpoint to relegate the LP to the rubbish bin?
I agree with Tvad, that you probably won't be getting a refund on a used record. I am sure the record store's response will be, "Hey, why didn't you inspect it before you bought it?".

(Even getting a refund on a brand new sealed record is no sure thing anymore. I've had more than one record store balk at refunding me money on obviously damaged vinyl.)

Good Luck!
Most people have their VTA set incorrectly. When it is properly set, the surface noise of an LP will be presented in a different plane from the music. Our sensory gating mechanisms can deal with this much more easily and tolerance of these abberations becomes much greater.
