- That's stretching a bit, but I'd be willing to concede that in some
- circumstances it might have a small effect. Not, however, enormous dramatic
- change. Perhaps a little buzz or other noise, not 'mushy bass' and 'treble
- all over the shop', etc.

- Anyway, it's often the golden-eared with outboard DACs that claim this
- supreme sensitivity. Outboard DACs, by virture of being in a separate box,
- should be well removed from the proximity of the servo motor. By virtue of
- their price, these DACs had better be well-shielded.

- What's left for the rings to do, other than color-code your disc
- collection?
