VAC Owners: Balanced or Single-Ended Cables???

If the runs are short agreed. However, for long runs the balanced will likely yield better results. I'm running about 15 meters and obviously using balanced.

5 Meters I would likely go balanced. 4 Meters it's questionable. 3 Meters likely SE. This of course would vary from manufacturer to manufacturer and environmental conditions. Low RF environments tend have less of a benefit with balanced than higher RF environments--so obviously this is just what I would consider reasonable starting points on average.
