The point about the way a record "sounds" indicates something about the cartridge and issues it could be having.This is very subjective and you must use your ears very critically listening for the small things.With a good table like a Rega P5 you should look for every clue.You should worry about alignment and not accept the Rega method as the last word.Many prefer a Baerwald aligment over Rega's as it gets better results with distortion.The sound and surface noise you hear will change with the cartridge model and alignment system you use.Records themselves must be cleaned even before their first play.The manufacturing process leaves debris in the grooves and surface of a record,which acts as missiles on the groove walls destroying a record, if the record has not been thoroughly deep groove cleaned first.If you are doing this(cleaning) and there is distortion,claim a refund or new copy.Many complain today about damaged new pressings from various companies.You could also have a damaged stylus which chews up records,do not play anything if ALL your records are distorting and get a professional to check your set-up.
