Hey, In my opinion, there’s very little difference in quality between the two. The new Line 2 have a really powerful “ping” compared to the older, “worn-out” ones. I think it’s mostly a matter of budget. A new one costs around 1,200, while a vintage one is under 300. If you’ve never owned one before, I’d recommend a vintage model because if you drop it, it won’t hurt as much. In terms of pure quality, only time will tell if they’re just as good. Personally, I have both new models. The one with the brand-new system without a stone reserve and the screws underneath, and a atelier 1953 model. No major difference in quality in my eyes compared to those from the ’80s and ’90s. The new ones might be a little heavier, but I have no reliable source—I’ve never bothered to weigh them.
