Very strange thread...
I have to ask - what phonostage are you using? I can't help but think that something else is amiss here. What you're looking for: "tight punchy bass, treble extension resolution and detail" are the very definition of what the 20XL excels in at its price point. I can't imagine any cartridge bettering it in these regards AT ITS PRICE.
The only MM cartridge I've heard in this price range that gives the 20XL's high end a run for the money is the Ortofon 2M Black. That being said, the 20XL is still a much more musical cartridge to my ears than the 2M Black.
For reference - I'm running the 20XL on a Jelco SA-750D with a light ADC headshell (resulting arm effective mass is around 12g) through a PS Audio GCPH phonostage.
