Also look into the Audiomods Series Six arm. The designer/builder started out using the Rega 300 tube in his earlier arms, but now uses his own carbon fiber tube, and manufactures all the other parts in his machine shop. A very well designed and built arm.
I have a Teres 245 setup for Rega arm. Question re Origin Live arms
RB 300 arm is ancient with a diy rewire. Having ground hum problems. Decided to upgrade and looking at Origin Live selections. My question is in regard to the wire upgrade value. For instance, should I go with Origin Live Silver or Zephyr with wire upgrade or Encounter with standard wire harness? Anyone with experience with these arms. I would like to keep in the $1500 range.
