VPI Classic vs. Well Tempered Amadeus

Correction to 1): the TAS review did not state that the tonearm had no resonance, but that "[s]ince the arm works entirely by damping, it naturally damps out the arm/cartridge resonance very well indeed. Running the Shure Era IV test record to find the arm/cartridge resonant frequency, one comes surprisingly close to finding no resonance at all." Nonetheless, my question still stands, i.e., how does this fit with the optimal cartridge/tonearm resonant frequency between 8-12 Hz?

No ring or clamp is recommended or necessary. I have a record that was unplayable on the first two tracks on both sides on my previous table. The WTA sails through this record like nobody's business.

With an Amadeus, I would deal with warped records by buying a Vinyl Flat.

Is any other WTA owners out there having the knot noise that Vortex mentions? Is there any option to relocate the power switch or have an external one since the rear switch would not work well with my wall shelf recessed into but not touching my audio cabinet.

I have no issues with the knot.

Not sure what you means about the power switch. Mine is on the top near the front.
