FWIW, I had a Lyra Delos mounted on a JMW 10.5i on my VPI Aries 3. I really like the uni-pivot arm and it was rock solid. I didn’t run any anti-skate and the delos tracked great and sounded excellent to me. I am using very nice lateral rack and have HRS E1 isolation bases under everything. I am on a concrete slab so the rack is spiked directly to the concrete.
I did have the aries table on a lesser rack on a wooden floor and the uni-pivot arm danced around a bit but settled in. A bit off topic, I wonder if those who don't like uni-pivot arms tend to have systems not on concrete?
I would buy another Lyra in a heartbeat.
