I've had my Well Tempered Original TT (not the Classic) since they first came out. In fact, the arm is one of the very first produced by Bill Firebaugh. I've never had one of the monofilament lines break. I have modified the arm somewhat. I have the heavy brass clamp around the arm well that greatly reduces micro vibrations and improves the overall sound. Also, I rewired the arm with Cardas wire and have a layer of shrink wrap on the entire length of the arm. Most recently, I replaced my worn and stretched out old belt with a custom made belt from Originlive.com. I highly recommend this belt. The WT belt should be replaced about every two years. When properly setup, the WT Classic keeps up with much more expensive tables. If you can find it, read Moncrieff's early review.
