There is more variation between cartridges than between arms so you're better off putting yr money into trying a different cartridge.
I have a VPI TNT 1 with 9" JMW Memorial arm. Then Upscale got me with a sale on the VPI Avenger with printed arm. This was the top arm a few years ago. Two decades of turntable evolution and I couldn't hear any difference using a Benz LP. Much bigger improvement switching from the LP to a Gullwing. There is no body like no body. The Gullwing combined the ethereal transparency of the Clearaudio Goldfinger with the rich sound of the LP. The best of both worlds - and cheaper!
* Lumi and Manley Steelhead phono stages.
No experience with Fatboy or Lyra but my datapoint chimes with what another poster said about VPI having a house sound.
Also have a Clearaudio Panzer with Universal and TT5 arms. And a Versa 1.2. In my observation more variation between cartridges than arm/turntable.
