I have a superb Audio Origami PU7 on my own LP12. A truly excellent arm.
However, it is also very important to upgrade other parts of the deck to get the very best out of any tonearm and cartridge.
you haven’t stated how old your LP12 is or anything else regarding the rest of the spec of it.
Disclosing the rest of the spec would be very helpful, especially as some older decks are not worth extensive upgrading. Also, other upgrades should be relevant to improving your current spec.
