Quick comment as I’m on holiday. It’s a very nice solid metal body upgrade costing about £200 for existing AT 500 and 700 series MM cartridges. I auditioned on an ARO using the styli from the 540 and 760 before sending it up to the guys at Loud and Clear for their evaluation. - They loved it too.
Worth waiting for? IMHO yes. Can’t say more due to moderation rules
