The Phase Linear 8000 turntable is the same thing as the Pioneer PL-L1000. Both uses a linear tracking servo tonearm. They can sound good but the weakness is the bottom platform that holds the motor and tonearm. It's made of plastic and it's rather soft and it flexes. The flagship PL-L1 corrects the problem by using a solid platform and no suspension.
The selling point of the servo arm is that it glides on rails and its actuated by magnetic force, just like mag-lev train, so it can servo correct bi-directionally. Most gliding arms only corrects for one direction a la Rabco and Goldmund. Very unique but the rollers are rather noisy. I gutted the motor out and build a turntable out of it. The motor uses Pioneer's famous SHR(stable hanging rotor) bearing--just a fancy way of saying an inverted bearing. They are good sounding motors but I prefer the coreless motors from JVC.
