Advantages:

1. Slightly lower inductivity.

2. Much lower electro-mechanical resonance due to the elimination of strand multiplicity if done right (as in Kimber cables).

3. Low DC resistance for given cross-section.

4. Flexibility.

5. Works well in braided cable construction.

Disadvantages:

1. Relative self inductance still high.

2. Possible corrosion in non-Litz configurations.

3. Does not cancel its own ring.

Ray Kimber's multi-filar braids are state-of-the-art in this type of construction and have found a home in high-end audio. Ray's combination has advantages and has stood the test of time. These embodiments are practical, flexible, cost effective and attractive.
