MC Cartridge Ideas

I'am looking to get a low output cartridge and need your advise and recommendations on which ones to research.
The Price Range is $2000-$4000.
The Sound I'am after is excellent detail retrieval (match digital) with pin point and spatial imaging and most important of all Huge Bass (sub bass slam and low extension)

I know its a hard question as most will recommend one or the other as audiophile we don't necessary keep swapping cartridges, but may be you are an audio dealer - Ideally you would be selling 20-50 cartridges and a few in my price range. Based on my Sound Characteristics you might be able to say Cartridge A is $2500 and surpassed Cartridge B at $4500 in the area of detail retrieval but not with Sound stage.

That's sort of what I'am hoping to achieve from this exercise, some in depth advise.
As with everyone I would like to keep the spend low but really go to the upper extreme its definitely worth it compared to the offerings at the opposite end.
