What is your source to make sure the carts are from the end of the 1980 while the FX series of the tonearm is from the beginning of the 1980?
They are from the same year (1980), your statement must be checked, but actually it doesn’t change anything. With optional W-250 counterweight FX series of the Fidelity-Research tonearm is suitable for FR-7f and FR-7fz cartridges from the same designer, but also suitable for lighter carts with different counterweight. This tonearm is more universal than its predecessor 64s. I didn’t said it was made exclussively for FR-7f and FR-7fz or FR-702 cartridges, but those cartridges were the best from Ikeda-San at that time and according to J.Carr - Ikeda-San is still proud of them. In my opinion matching the best products in color is also a good idea for those who cares not only about the sound, but also about aesthetics.
The black body cartridges started at the end of 1980.

Why you said: " and supposed to be made for each other."" when the tonearm appeared at the begening of that year and the cartridge at the end ! ? ! ?
