The ideal way of extracting the exact signal as present in an LP groove must be with a laser, making no physical contact at all. How that relates to either the signal extracted by a top class cartridge or the original signal that was sent to the cutting head that made the master disc is a matter for speculation.

Personally I have more faith in a digital chain, provided that each stage of that chain is well designed, than in a chain involving a hard stylus rubbing along the sides of a groove in a piece of soft plastic. But each to his own.
