Ack,
I'm not sure that I understand your comments?
In all my videos with both Victor TT-101, Victor TT-81 and Raven AC-2......the Timeline and KAB Strobe are shown with tonearms lowered and raised.
In fact they are the only videos in this Databank which show this situation.
As Lewm has stated.....the weight of the Timeline clamp or the record clamp are irrelevant as weight is not a factor in stylus drag and certainly weight over the platter bearing plays no part.
Stylus drag is caused solely by the friction of the stylus hitting the walls of the record groove with enough force (and on enough occasions) to slow down the rotational speed of the platter. This will occur more noticeably with heavily modulated passages where the vinyl walls can be almost perpendicular to the path of travel of the stylus.
With both Victor DD turntables....it is apparent that even with 3 tonearms lowered or raised in any combination......no change to platter speed is visible with the Timeline.
With the Raven under the Timeline....it can be seen that the platter runs slightly slow with the stylus engaged but runs perfectly to speed when the tonearm is raised. However with the KAB Strobe in place......it appears that the Raven runs perfectly to speed with or without the tonearm engaged.
Based solely on the visual results of the KAB.....one could possibly claim that 'stylus drag' is a myth?
The Timeline however proves that it is a reality.
Now the AMOUNT of stylus drag with the Raven is very small........and because it appears to be relatively consistent....it is inaudible.
So it bothers me none that the KAB Strobe is 'good enough' for all practical purposes and if Lewm and others are happy to rely upon it.....who am I to argue?
My only disagreement comes with the claims that it is as accurate as the Timeline?
Now if I have misunderstood the points you have raised.....perhaps you could put them another way?
