I owned a Colibri and liked it, but I like other of my cartridges better. Since vdH make a myriad of versions of each of their major lines, it’s quite possible I’d love some other vdH, maybe even a different version of Colibri, better. But I don’t generally choose a cartridge based on lifespan of the stylus. Nor do I know of any data to support the notion that vdH styli outlast all others, though of course stylus shape seems to affect useful life span, or so I have read, and it makes some sense.
So you’re suggesting that vdH exclusively uses a stylus shape that renders its useful life significantly longer than any styli used by other makers(?)
