The XV-1s is a GREAT CARTRIDGE. It could be your preference to the Blackbird but you might think differently about the XV-1s with a different setup. Maybe the Blackbird is a better match with the JMW 9.
How good does a TT have to be for a good cartridge
I have often wondered would you get good sound from a really good cartridge on a decent but not super good table. I am not an analog fanatic. I do own two fairly basic modern tables. One is a plain VPI Scout and the other a Music Hall MMF 5. Could I expect great sound from either one with a very high caliber cartridge that might cost lets say $3-5K . Is this an example of not being able to put lipstick on a pig?
