To answer what cable would I use with an absolute top flight server/streamer & DAC? As I have only had experience of the manufactuers I listed I would have to say I would stick with Artisan Silver Cables who offer a 'better' version of the USB I have. Using the direct sales model seems to enable them to sell at half to a third of the price of the well known brands. This applies across all the cable ranges they do.
There are a number of online reviews of their different products and all seem positive. Another positive is that they rarely appear on the used market.
When funds allow I will be taking the plunge with their interconnected and speaker cables. As already noted with a 30 day money back guarantee there's little risk.
Just to clarify I have absolutely nothing to do with said company.
