Want to upgrade my cartridge from 2m blue to black

@bsmg he could ask any Ortofon dealer about it online. 

@tubelvr1 If the Black stylus is so expensive i would recommend Ortofon M20FL Super with nude FineLine diamonds. Great cartridge that can be find NOS for about $200-300 or even for a lower price. Seach on audiogon forum for user feedbacks. I still have NOS stylus for it, but i don't have cartridge body. 

Ortofon’s site says the black stylus can be swapped into a bronze body but does not mention any other swap. You need to be wary of NOS old cartridges; the stylus suspension can / will deteriorate and become stiff over time.

The Black stylus can be swapped into any of the 2M bodies the difference is that the "better" ones gets selected for the Bronze and Black - the runts for the Red and Blue.  The electrical specs are listed as 1.2kOhm for the Bronze and Black - 1.3kOhms for the Red and Blue.

Be careful pulling the the wire leads of the 2M series the cartridge pins can pull out if the clips are too tight.  

Good Listening

It happended only with 2-3 cartridges out of 60 that i've tried, and those carts with bad suspension are Technics EPC-100 and EPC-205 series. 

Thanks everyone for all your suggestions. My maximum budget is approx $700 so I thought this would be a worthwhile upgrade to my analog play back. I understand the limitations of the turntable and I am told the black is very critical in picking up noise from dirty vinyl. I will also be using gruv glide to treat my vinyl collection.
