The question to me is how you evaluate this in the real world, given the limitations that most brick and mortar dealers have, aside from their choice of top tier brand(s), which may limit you.
Late last year I asked Upscale Audio in LA [I think one of the bigger places out there] to set up a demo to show that there are differences in sound just from plinth-arm, so two set-ups with same cart on same electronics. Their choice of tables, carts, anything, just to see whether plinths-arm actually makes an audible difference. They flat out refused. And I have been a repeat customer with them.
So I blind-bought a Rega NAIA package. All the grandstanding "never buy anything without auditioning it first" does not work in the real world. Is there anything better, something I will like better? Maybe, but I will never find out.
