Graham Phantom vs. Phantom II

Hi, I own the Phantom and think about getting the Phantom II.
It is quite rare, but is someone out who did the change from one to the other?
When yes, may I ask, what do you think about the sonic differences. Some say there are none but I think from technical paper there are...

Thanks

If possible, what was the serial# of your Phantom I.

Your physics seems to be faulty here. Assuming that the counter weight is indeed firmly connected to the tonearm tube (which is always the case in a well designed pivoted arm), then, the effective mass of the arm must be dependent on the distance of the counterweight from the pivot (ie. the moment of inertia “I”is dependent on the radius squared). The composite "I" for the arm tube/counterweight and subsequently the "effective mass" would essentially have the same dependency.
