I read recently that the most important part of a phonograph system is the turntable, followed by the tonearm, folled lastly by the cart. It doesn't make any sense putting a $5K cart on a $400 TT/Arm. I would recommend selling your two tt setups and buying one new one of the best quality TT and Arm possible and run it with the cart you have now.
Looking for the best moving coil cart that is around $5K used
I currently have a Dynavector drt xvs1 and am looking to upgrade. In my experience, the TT has little to do with the sound. I have a $400 Pioneer PL 71, and It gives me just as good of sound a my VPI-Scoutmaster . I’m looking for a used moving coil cart around $5K. I like clear sound, not too bright, but very articulate and good tight bottom end. Please give your suggestions and why. BTW my phono preamp is a Rhea Signature with new low noise tubes. Sounds great, just looking for the elusive unicorn
