I have owned a MintLP (Rega), Dr Feikert 2Gen, and now a SMARTractor. The Feikert and SMARTractor were used with a VPI JMW3D arm. The SMARTractor is the best by far, and most expensive. I am dealing with cartridges in the range of $2800 to $6500 so the $550 I spent on the SMARTractor is money well spent. I was not that impressed with the MintLP on my Rega RB2000 arm.
Dr. Feickert Protractor
What will Dr. Feickert's protractor do that the paper alignment protractor that came with the turntable can't do?
