I'd try and snag a Shure m97xe, if you can find one. It's a great mm cartridge with styling cues from the shure v15, with the drop down stabilizer brush. To me it's a great sounding mm cartridge.
MP150 or MP200
I am currently using a Nagaoka MP110 cartridge and want to upgrade . I really like the Nagaoka sound and was considering staying with the Nagaoka sound . My question is will I get a considerable upgrade in sound going to the next level cartridge which would be the MP150 which would be a 329.00 investment or in order to get that big upgrade I would have to go to the MP200 which would put me almost at the 500.00 mark .
