I suppose it is possible to have a cartridge aligned well-enough for, say, an elliptical stylus, which you then change to something more advanced, and suddenly you find you need a more accurate alignment?
I'm becoming more nervous about installing anything new, as I don't want to upset the applecart. And it's probably true that the longer I keep gear, the more my brain accepts its sound as the way things ought to be. All of which is good for my cachectic bank balance. So if you find your results are amazing with your current stylus, you might think carefully. Might you be better off buying a couple of records rather than the stylus?
