MK2 = It’s way overpriced, less stable, more bricking or freezing possibility, stupid marketing bass frequency ranges talk, ugly looking grey faceplate, …
Looking back in history of synth, etc all first units seem to have ‘that magic’, 'flavour", collectors item, etc The first is mostly the best in many cases like movies, gear, albums, books,etc! You will feel super happy when buying a supercheap underrated synth like A4 mk1! Too bad it does not have some sort of poly chain or I would have bought another mk1!
