Right cable for the right component. You don’t want too heavy a cable for your source, just like you don’t want too light of a cable for your conditioner or your power amps.
Thus, “best” needs to be viewed in context of HC vs Source. I would put your best HC cable on your conditioner. I would experiment with source cables on your preamp, DAC and transport. It will come down to which one had the most sensitive power supply.
