@lewm I'm not sure I understand your question or the logic behind it. Any re-tip is the cost of the cartridge plus the re-tip.
The cost of the re-tip however is a fraction of the cost of a new cartridge of similar quality. In this case, the cartridge was included with a turntable that I paid $500 for, so it didn't cost me much, if anything.
Again, I have no idea what it sounded like before, but I have to believe it's an improvement. I wasn't expecting much and was more than pleasantly surprised. I do have a couple of Denon DL-301 MK2 cartridges, which is a higher model than the DL-103 and the re-tipped Zu Denon is in a completely different league.
