I thought I was in the clear, but now I’m informed that a Contact Line Diamond stylus with three times the contact area, picks up a ton of surface noise off the record. So much so that the surface noise can become forward on all but the most pristine records. So much so that the surface noise becomes intrusive.
If this statement could be true then the best stylus would be Conical, but it’s the worst ever. So the advanced profiles will bring you the music, accuracy and less record wear. However, comparing to MicroRidge his Contact Line is not an improvement, but also very nice profile.
When people proceed with SoundSmith retipping i would ask why not just buy SoundSmith MI cartridge instead ? Only his own cartridges were designed for use his cantilevers/diamonds. Cartridges from other manufacturers designed for use with different cantilevers/diamonds and it’s a complex question why "x" cartridge is better than "y" cartridge.
Your Dynavector is a $850 cartridge and you can buy plenty of amazing cartridges for the same price or even lower.
Maybe it’s time to try something different? Or you are so in love with DV-20x2 ? SoundSmith can definitely bring your Dyna back to life, but if you like his vision i would look at his own cartridges instead (they are reasonably priced and he could service them at very low price too).
