Is DTCD the most important or only factor to consider in building the best AC distribution system?
There are of course other factors involved in building an exceptional power distribution system for professional and consumer A/V systems. DTCD represents the foundation, or base of the pyramid that has to be in place for the other qualities and elements of an AC system to be significant. If there is degradation to DTCD for instantaneous current then the benefits of noise isolating properties will be all but wasted.
