Sure, but I'm not understanding how one can attempt to determine the quality of the SQ from a cartridge that is playing a crappy LP??? OTOH,Test records that are played once and destroyed are going to be an expensive replacement on an ongoing basis. Buying used is a crap shoot...and one that i personally am very hesitant to undertake. Better to buy new and make sure that you have done enough homework on the cartridge in question to be fairly sure of your purchase. ( albeit, still a little bit of a gamble, as who knows the real synergy with your system and room until you try).
At least you won't have damaged vinyl in the process...assuming you initially get the cartridge set up correctly.
BTW, I will not use an expensive cartridge on a G- uncleaned LP, stupid practice IME.
