Frogman - I hope you don't mind me referencing this post.
But it was a sort of an - awakening - for me in truly understanding how this ET2 works.
IMO - based on my own experience
If you want to get at beyond - lets say for example 7/10 with the performance of your ET2, you need to understand how the I Beam tuning can work for you in your own room/setup as it is a resonance hobby. The resonance of the Ibeam goes higher with a stiffer IBeam - this has been discussed here.
Play with it - make it gel with your cartridge.
fwiw - at this point even with a single leaf spring and no tuning it is still my reference tonearm. This tuning just makes the delta bigger with the others.

****Throwing weight at the I-beam near the spindle pivot does not increase the arms rigidity.****
Exactly.
BTW, there is a (not particularly elegant) way to experiment with lowering the I-beam compliance without use of the double spring. You can wedge (carefully, of course) a very thin piece of some very rigid material cut to fit that space, into the cavity between the spring and outer end of the counterweight cap/clamp. This will effectively allow LESS horizontal movement of the I-beam. I think you will all be very surprised at the
difference in sound.
Ain't this fun?
