Agree with Curio. I can think of many problems that are more likely to cause mistracking (or mistracking-like sounds) than a tonearm. I've diagnosed mistracking sounds on quite a few setups, and in no case was the tonearm itself to blame.
In some cases what sounds like mistracking isn't mistracking at all. Vinyl pressing voids and various phono stage issues can emulate mistracking noises well enough to fool most of us, especially in an unfamiliar system.
To conclude that such sounds were actual mistracking (without verification) and then attribute blame to the Phantom (without being able to investigate other, more likely possibilities) seems like two assumptions in one.
Not a Graham owner, just a disinterested observer...
