The existence of a tonearm fluid damper as an option: Does this mean that the stock tonearm is completely undampened when lowered onto the record? That is crashes down on your record with the full speed of gravity? This sounds incredible/unlikely to me and I am just trying to understand. :yes:
Thanks.
I think you're confusing two different issues.
1.
The cueing lever is damped, so that when you use it to lower the tonearm, the stylus slowly and gently contacts the record.
2.
The design of the tonearm is such that the bearings are very free moving. Thus a warp will cause the tonearm to move quickly in response, sometimes to the detriment of playback quality.
The optional tonearm damper is a small paddle that attaches to the side of the tonearm. This paddle rides in a trough filled with heavy silicone fluid. Thus if you're playing that same warped record, the resistance of the paddle in the thick silicone fluid slows down or dampens the quick or sudden tonearm movement caused by the warped disc, resulting in better tracking and sound quality.
Some tonearm designs are such that dampening is achieved in a different manner. A thick silicone grease in the tonearm bearings is a common method.
