In fact, I also own a FR-Mk3f thanks to Nandric, which sees regular action on a Micro Seiki BL-91 with a Fidelity Research FR-64S and can truly confirm your statements, ateal. I recently purchased a NOS John Marovski Mirror Image Transducer MIT-1 cartridge (essentially a "tuned" Coral MC cart with a Van den Hul diamond) from Nandric as well, which was striking in its display of music and possibly even more detailed in the treble than the FR-1, but the FR-1 struck me as being more live-like in the sense of sounding more natural and it was clearly more detailed in the mids than the MIT. That said and to be fair, I only test-ran the MIT and it has not seen any play-in time yet, so this comparison is likely premature.
I have not heard any other upward comparisons yet, only downwards to my parents Dual 505-4 with Ortonfon OMB-10 MM cartridge, which it clearly beats in terms of resolution and clarity across the entire spectrum.
Do you play your FR-1 using a Step-UP Transformer? If not and you think it's great already, just wait till you hear it using e.g. the simple Fidelity Research FRT-3 SUT and watch how it comes alive... THEN you've got your step-up improvement and you need no more :-) no pun intended, but still befitting.
