IMO, there's nothing wrong with optimizing sound from one component to another using cables that sound best in that position, whether they're from the same manufacturer or not. I know most cable manufacturers will suggest using the same wire. I've only heard two systems that use the same wiring for ICs and speaker cables, and both systems sound quite good.
I've recently replaced 80% of my power cords with a particular model from one manufacturer, and I believe I hear benefits by doing so.
