My love to Ikeda & FR tonearms getting stronger.
I'm a junkie about NOS vintage gear, i couldn't ignore Fidelity-Research FR-64fx in NOS condition in original box with documents (complete set). What a wonderful tonearm! Arrived this week, this is really a state of the art design. I like its black finishing, each time i compare it to the FR-64s i like the 64fx better. I've been using another sample with W-250 counterweight for FR-7fz. It's funny, but looking just for a small counterweight i ended up with another sample of FR-64fx (NOS) with this counterweight. So now i can use this arm with conventional cartridges (higher compliance). 
Wonderful. The general consensus is that the S is superior (of course cart compliance is a factor) but this is yet again proof that there is more than one answer to most audio questions ;)
I only have the FR64S so can't compare...
