I'm curious as to why someone would do a conversion to a (relatively) cheap (price-wise---I've never heard it) cartridge from the B&O standard? Is there something to be gained here? Looking at the Grado Gold prices they sell for $220 and that's half of what an MMC1/2 would go for?
I guess if you really use the deck a lot, a replaceable stylus will be a big plus.
