Tweaks

The latest issue of Absolute Sound has a list of 15 or so tweaks that they say are worth doing. I would like to get some feedback from others about 3 of them.

1. Grounding Caps for unused preamp inputs.
2. Equipment anti-vibration devices such as Vibropods.
3. Aligning interconnects and power cords so that they cross at right angles to each other. (This sounds like a very difficult thing to arrange).
