About 14 years ago I had my ruby re-tipped by Van Den Hul. I had this done because I liked the sound of Van Den Hul stylii. The results were as I hoped, and I have never regretted my decision. The cartridge does sound different since the re-tip, but that is what I wanted. At that time Van Den Hul wanted 600 dollars for a re-tip, I think. It was about half of what Benz charged. The turnaround time was not too bad, about 6 weeks, but that was then.
