Cartridge upgrade


I currently have a VPI Classic 2 with a Benz Micro Glider medium output cartridge. I am thinking of upgrading but am not sure what price range I have to go to to get meaningful improvement. For example will a $`1500 budget do it? If so what to get? Thanks.

I also would consider Raul’s suggestion of the Ortofon Cadenza Bronze. I loved its presentation and after years of intense use I sent it back to the factory for a complete rebuild. Moved to the Ortofon Windfeld Ti so it now remains new and unused as a backup. Haven’t been able to part with it though I love the Windfeld...
