So does this mean the speed should 'not' vary on the turntable once you have removed the Timeline. I would have thought that given the weight of the Timeline, having it on or off the TT, would cause a deviation in speed.
The Timeline is maybe 8 ounces, little more than an audiophile LP, I don't think that's a factor.
Or am I completely off the track here in understanding, where stylus drag could cause speed deviations but having the Timeline on or off the tt wouldn't?
A small weight above spindle is not the same as variable drag (friction). My preferred clamps are several pounds AND lock. My turntable is powerful enough that weight is not a factor, so I get all benefit with no downside.
With Timeline and my mat the LP slips. No way to "push down" and lock to simulate more weight. However, making Timeline a locking device would drastically change the price and benefit few. (This is my opinion, no input from Ron Sutherland).
The reason why I ask is that once the speed is set with the aid of the Timeline, does the unit then just sit on a shelf.
For me, yes. Same as my stylus force gauge, Mint tractor, Wally Tractor and other tools. If the Timeline works on your turntable as a weight, you got a bonus. I think it's worth the price as a speed check alone.
Would you check speed weekly/monthly.....
As this would then makes it easier then for a few of us audiophiles to purchase one unit and use it between us when required. (As I don't see them for sale on Agon as yet)
I must have my own tools, things always happen at the wrong time, hard enough to keep everything 100% even with everything handy.
