And you make wild swings sideways time after time:

We can go..FORWARD or BACKWARDS! ???..
Chasing after the Essence electrostatics (no longer distributed in the US),
Bose 901 (40-year step backwards),
Yamaha Soavo NS-F901 (came and went in less than a year), and speculating that they're pushing TAD R1's off the market,
"Modified DCM TFE200's......World Reference Now",
... and more breathless be-all and end-all product rhetoric than I am willing to track any further.
BTW, your link to Princeton U's measurements of the Essence 1600 show that they start rolling off in the "bass" at 320 Hz and are down 16dB at 100 Hz. I don't expect any better bass performance from a stand-mounted electrostatic, let alone 20Hz at -3dB.
