I know what you mean, Rockinroni. I'm already fighting the battle with static. This time of year it's bad one day, completely gone the next. It also takes about 2 hours to lift the temperature in my listening room (finished basement) using only the heat from my system to warm me and the cartrige suspension. It averages a 5 degree rise, but I'm saving money on the oil bill by not having to turn the heat zone on down there. At this rate I could pay for my stereo equipment in 100 years or so.
I am coming around to the idea that level is the best place to start. I have read about cartridges being made so that their stylii are set at a certain angle with respect to the body, which is usually spec'd at being parallel with the LP surface. Beyond that I'm joining the camp who believe that you should set the arm to what ever is needed as dictated by what angle the stylus should be at to properly trace the groove. Now that I have a better feel for dialing in from scratch, it does seem that this optimum setting is generally going to be within a few degrees of level, but that is really not the goal. That is, the goal is not to keep the arm level as much as it is to get the arm in whatever position it needs to be in so that the diamond is in the proper attitude with respect to the groove angle.
That's all I can manage for now, Jack is calling my name. And loudly!
