Sony is rare and not so popular, you will not find much info about this model, but Sony is better cartridge, it has Boron Pipe cantilever while Grace F9 has aluminum (or Ruby if you're lucky). I have both cartridges, my Sony XL-50 is mounted on dedicated Sony Soundtech headshell made for this cartridge, here is the only picture of my Sony.
It's not easy to find a perfect sample of Sony XL-50, the performance primary depends on condition. Since my Grace F9 and Sony XL-50 are both perfect i can confirm than Sony XL-50 is much better cartridge.
How's the Sony XL-50 stack up against the F-9 Grace?
