Alright here is a few quotes from the thread over at stevehofman you have probably read this already but,
"I ended up ordering a Shibata-tipped VM95SH cartridge. I'll lose the wood-body of the Virtuoso but whatevs."
"You won't loose anything; Just tuck out the old stylus, inserting your finger nail, or a toothpick in the back of the stylus assembly, the black plastic to be clear, and then insert the vm95 stylus replacement, That's all "
"I think with the V1 version of the Virtuoso, you can just pop off the name plate on the front and install the AT stylus without any surgery after removing the old stylus, if you want to compare what the Clearaudio body mods bring. I don't think it will fully seat without removing that front plate, but @Danilo above thinks it will, so maybe no need. Or get one of the ML stylus assemblies and try that in both carts compared to the Shibata you ordered."
looks like you just need a at95 series stylus some good careful prying and a steady hand, no idea how it actually is in practice I own a grado stylus that makes swaping easy
