Take a good look at the Lyra Kleos or Kleos SL cartridges. I just bought the standard version and really love it. Great reviews all around on this cartridge so read them and determine if it's the right direction for you. I previously owned a Lyra Delos and a Kiseki Purple Heart, both of which are excellent cartridges, but the Kleos is as good as I've ever heard. Mine is mounted to a SME IV tonearm so a Kleos should play nicely with your V tonearm.
Cartridge recommendations
Hi, I have a Thorens TD124 that was sent to Schopper in Switzerland and has every upgrade available that Schopper can do to this turntable including motor upgrade and service, upgraded platters, Schopper chassis plinth and Schopper decoupled armboard etc etc etc; I recently purchased an SME V tonearm for it. As you can see, I have spared no expense to this point; My last step is to pick a suitable cartridge; Looking for recommendations. My first turntable; Thank you.
