I had my Lyra Skala rebuilt by Soundsmith, and didn't especially care for its new sonic signature. IMO, the difference in cantilever material fundamentally changed the sound of the cartridge. It's not bad per se, but it's no longer a Lyra. I don't think I'd send another cart to Soundsmith since I think their generic 'one size fits all' approach seems a bit heavy handed. I'm going to send it to Joseph Long, and see what he can do with it. He seems to have a wider array of materials (including boron cantilevers), as well as identical profile Ogura diamonds. His backlog is lengthy however. Just my 2ยข.
