Ortofon 2M Bronze vs 2M black any difference?

It has the stock arm a RB808 Tonearm, and i am getting some spacers put on too, for the arm.

For the VTA issue. But dose the 2m black have different internal wiring I thought it was only the styles was the only change.

I am not aware of any internal wiring differences,  With the exception of the stylus and extended high frequency response of the Black, all other critical specs are the same.

I replaced the Bronze with a Black
Another world. The black is way superior in every way

For the price of 2M black (shibata) you can easily find nos Stanton 980 or 981 (both with stereohedron stylus), those cartridges are way superior to modern Ortofon and most of the top vintage MMs. 

My friend replaced his 2M Red yesterday with vintage nos Stanton 881s mk2 i gave him (official Doug Sax / Sheffield Lab's studio monitoring cartridge). He said it's a huge improvement over the ortofon.
