I actually bought the turntable with the 17D3 Karat, but the cantilever broke a few years back. It was an awesome combo and then I got the xx2 which improved on the bass. Time to get a new cartridge.
I see, new cartridge is always good idea. Compliance for KARAT series is 15cu but most likely measured at 100Hz like all Japanese carts?
If it was measured at 100Hz then when we convert it to 10Hz is will be about 27cu.
For example Koetsu Black compliance is 5cu @ 100Hz (about 8.5 @ 10Hz) and this is very low, another heavier arm tube must be used for such low compliance cartridges.
