Hi The Sonata and higher Grados seem to be different animals from the lower ones. Mine tracks the Analog Productions Ultra test LP fine. A scope shows no issues at all levels. My sense is that the cartridges may be more sensitive to arms and set up than might be common. I use a Jelco 370H (9") with a 1.5 gram VTF and just a little less on AS. It is set with a Baerwald alignment. The damping on the arm is at nearly minimum. I didn't test any of the other Grados that I had (all sold off now) but I really didn't notice any audible tracking issues with them either. Possibly synergy between the arms and the cartridges. Don't know and above my pay grade. YMMV
