They're not the only option. ( http://www.vandenhul.com/products/phono/cartridge-repair-modification-and-re-tipping-available-services ) I highly value experience/expertise.
Soundsmith is not the only game in town.
I sent Andy at [email protected] my Lyra Helikon for stylus straightening and a complete tune-up. Not only were his fees reasonable but his turnaround time was as promised, less then 2 weeks! Obviously Peter @ Soundsmith is in over his head when it comes to cartridge repair, believe me, I tried. I just wanted to share my experience with Andy. Highly recommended. By the way,the cartridge sounds and performs as new.
