Mine is close to evenly split between tone arm and cartridge. With about $5K arm and $6.5K cartridge. You can do well with quite a bit of variability. I have heard some great systems with 2 x or more on the cartridge... or 2x on tone arm. I think with the dedicated isolation platform and tt... Have another $10K in the table, and $20K in the phonostage.
Do you spend more on your cartridge or tone arm?
Is there a rule of thumb on the dollar ratio between the cost of your tonearm and amount spent on your cartridge? Assume a $5000+ turntable.
