The only Fluance turntable that has crossed my path had noticeably loose arm bearings. This might be a peculiarity of the sample and not common to other units. Check yours for any play in the bearings, and if found, investigate whether it can be adjusted. In my experience chattery bearings are usually not the friend of MC cartridges! If you want to upgrade from a 2M Blue, consider the AT-OC9XML, Hana ML, or Sumiko Bluepoint 3. Hana and Sumiko offer high output versions if your preamp is fixed gain at 40dB.
Is a Fluance RT 85 turntable worthy of a moderately priced moving coil cartridge?
I purchased the turnable and accompanying moving magnet Ortofon Blue cartridge a couple of years ago and it's been flawless. Because audio is a hobby Id like to try out a moving coil cartridge and want to make sure Im not trying to put a big block chevy engine on a go-cart, if you get my meaning. I do have a phono pre amp that will handle any cartridge type and output.
