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?

Elizabeth, I agree that the most annoying ones are the clean looking ones with constant noise, even after cleaning. Is there any way one can tell by looking at the grooves in sunlight whether this will be the case before buying?
"Forgot to add: the clean looking LPs with the dreaded constant surface noise (cleaning often will not fix) are trash. please destroy them if they are not a rarity."

Please do not do this! You may later find that you cleaning method was not sufficient and trashed many otherwise good (and irreplacebale) albums.
