Hi D.
your 20 set LP reference is an interesting suggestion --- though it seems grounded in trying to get some form of 'perfection' where it can not be gotten.
When my audio-friend has often a hard time to find consensus listening to the same record / same system as I, gives me the idea it can only get more difficult, not less.
Next, a good product will not be 'sunk' just by some divergent listening impression. (They still make and sell SME arms and others, despite some hefty criticisms, that I do not have to repeat, yes?)
If 'perfection' was the goal we could close down every forum and junk every specification, as we know that the ear has it's own ways.
I think your quest for perfection, where there is only so much of an approximation possible, gets into your way more than it helps, in fact you know this too well!
But like a Sheepdog you can't help your nature, and keep chasing the 'bus' :-)
Now, if I want to verify some listening impressions in the forum and find mine either completely contradicted or affirmed, I have learned something!
This in turn can be synthesised into either a new or different understanding, and so on.
If you say: "I have no questions..." then you are done, finished. Yet, we are never to old not to learn something new.
In some other thread I ask for listening impressions of two carts, based on how they sound in my system.
If someone else hears them differently I have two option:
1) tell him that he is wrong! Well I have my prove or?
2) thank him, and go back maybe with his good suggestion and see what I now will find, and I have learned something.
It's all about information acquisition and synthesis, and NOT about refutations, at least in a forum.
Looking for spreading your one and only truth?
Get a soap box, stand on it, preach, make disciples :-)

PS: The FR is truly a beautifully machined/manufactured tonearm, no idea what it sounds like.
Probably very nice in my system, since my system sux, as I can not hear any difference between dynamic an static VTF either :-)
