Yes - I sent him a Linn Kandid and he did a kick-ass job. The Kandid is tricky - it has to have just the right suspension work to align the coils and magnets at the exactly specified tracking force, and also uses a 3-point mounting scheme, where the stylus overhang must also be exactly right. His experience with Lyra cartridges suggested he might be a fine choice.
Well, Steven got it as perfect as my eyes and Feickert protractor can determine. He made sure to send detailed before, during, and after photos in order to prove the necessity, thoroughness, and precision of the work. And he did all that at a very reasonable price - in fact, he held to his original repair cost estimate even after he found an entire cantilever replacement was required in addition to the quoted work. Personally, I won't hesitate to use him again - which is great since I have a customized, medium compliance, low output Van den Hul Frog that has a worn stylus. I believe you can use his service with confidence. I certainly will again.
