"when the sylus goes up in the air the VTF changes. when the sylus dips the VTF changes. with a dropped counterwieght the theory is that the changes in VTF are beneficial in that they keep the stylus from digging in and rising off the record. Some contend otherwise."Exactly so. What advocates of the solid underslung weights are not taking into account that an arm tracing a disc is a 'dynamic' system, not a 'statically balanced' one.
IMO the sonic benefits of an uderslung weight are not to do with tracing (at least, in a Rega) but with with balancing/stabilizing the load on the two vertical bearings, i.e. stabilizing the whole beam assembly in the 'roll' plane (that aircraft terminology again). I believe this benefits the way the bearings transmit audio-band vibration to the pillar and hence to 'ground'.
Were thet spaced well apart in a yoke, rather than pressed into short stubs in the Rega's tube, it wouldn't be a problem.

- They are equidistant, at least on a 250. The 300 and up may be a different story. - Garth 13:45:00 09/11/06 (7)
- "They are equidistant, at least on a 250." - ahem, and this is another reason why the 250 is better than the 300 [nt] - OMalley 14:50:07 09/11/06 (1)
