Yep, I discovered that a couple of days ago and sucked the .gif into the Empire phototorium. It's not the sharpest macro shot, but at least you can see what Steve at turntableneedles.com calls the magnets
[UPDATE: They're not magnets.]
Hats off to Steve at TTN.com for this gif and other unique identification tools.
EMPIRE 800 UFR STYLUS GIF FROM TURNTABLENEEDLES.COM
To answer your question about inductance and voicing, we know some styli must be voiced differently from others because of the wide range of inductances used. The 2000Z/T twins are spec'd at ~650mH but measure over 800mH in my three samples, one of which is an EXL 30. If you need that much inductance (which means that strong of a low-pass filter) to reach flat response, you know that stylus has a rising response somewhere in the audio range.... compared, that is, to a 4000-series stylus that only needs 250mH to arrive at flat.
The body inductance is always as high or low as it is for a reason, and the reason is to bring the response of the cartridge as close to flat as possible. Other good examples of this are the story of how the XSV-3000 became the 881S, or how the ADC Super XLM Mk II stylus can be "tamed" by putting it in a Mk III body.
I've too often told the story of my expensive S77LAC (equivalent to a 600LAC) arriving and sounding like the high treble'd been lopped off when I put it in my 300 Z body but sounding Aaaaahhhhhh when snapped into my RM 50 body. In my system, the difference was clear and obvious. In someone else's system..? Too many variables. Maybe, but maybe not.
I wish we had specs on the UFR body [see post #1303]. It may be a second-generation design, which means 700mH which means sounding good in an OP 4 body. It's encouraging that the canti on the UFR looks like the one on the 2000Z-- maybe it's the exception to the 0.6mg rule the other Chunky styli follow. [It is!]
The 2000Z is weird not only for its high inductance but also for its laminated magnet structure (16 layers!) and of course the teensy shank that admits no lesser styli, a la V15 Type III--V. Maybe the 800 UFR is the Chunky 2000Z [It IS! see post #1303], in which case I'd expect it, like the 1080 LT, to have a 700mH body [It does!], which as I said would let its stylus sound great in an OP 4 body (also 700mH). I believe the UFR's magic is entirely in its stylus.
And by the way, the 1080 LT sounds great too. I'd like to be able to compare its stylus to the 800 UFR's.
