I'm thinking of upgrading my cartridge from a goldring 2100 to the slightly more expensive 2200. Looking at the specs of both, the only difference is a jump in internal inductance from 550mH to 680mH in the 2200. The other things that appear different about the 2200 is a plated alloy cantilever and super permalloy poleshoes. Does this feature distinguish itself from more budget-level cartridges? What about the inductance. What does it mean and is it very significant? Looking at the most expensive in the goldring "2000 series" the 2500 model has inductance of 720mH. I'm not looking at spending a lot, just want a little more out of my system (and maybe a bit of advice on value for money on a mm cart) I have the phono box S which has switchable input impedance/capacitance. For the record, I was happy with the sound of the 2100. The series is generally regarded as "bright" which I don't actually have a problem with. Appreciate any input.
