Frankly, I'd go with the idea of (at least eventually) a better TT, and buy a used ADC XLM or ZLM body and equip it with a Shibata stylis from JILCO in Jampan. Total cost; no more that $250, and one of the bestt mm cartridges ever made, upgraded even further by the shibata stylus.

Seems you can go crazy with cartridge costs.I have a Prima Luna primium hp, a pro ject ds tube phono stage and a pair of Focal Electra 1028 Be. Appreciate your input.
