I like reading threads like this as it teaches me something. Ron's comments about lateral stability coming into play with the Denon 103 are quite interesting to me. You see, all of my arms are linear trackers, so their level of lateral stability is infinitely higher than that of a pivoted arm. I might not have ever come to any such conclusions due to the completely different nature of installations. I know that Twl has made comments to this effect in the past, but for some reason, i never put 2+2 together in this area before. As such, keep up the good work guys. You're teaching all of us dummies something we didn't know or might not have ever considered on our own : ) Sean
