It’s a good thing and fun to have several carts and rotate themHi Aziz - I"m more aware than worried.I try not to get to that point.
I have several cartridges (listed under my system link) and rotate through them ... maybe make a change every 4-6 months. I will buy a new cartridge maybe every 2 years, but the hard part is finding the right cartridge for me -- I found my last one through review. Now that my tonearm universe has expanded with the 3012R there should be more opportunities. I have never re-tipped a cartridge.
