Where would you put better power cable?


I am wondering if my better power cable should be on my dac or transport. Both cables are nice but I am looking for advice. Currently I have my pricier cable on my dac being a thicker gauge with better connectors. I am using a 6sons audio Vision Quest on my transport and an Audio Art Statement 1 on my dac. Both cables are nice but the Audio Art cable may be superior. It's hard to tell. My best cables are on my Hydra's from the wall. At least the cables to my Hydra would be the priciest cables. I have Audio Art Statement 1 cables to my amp, preamp and headphone amp and dac with good results. I have a Tekline cable to my tuner which sounds nice. The Tekline cable is quite nice but I'm using the Statement 1's for a change. Advice would be appreciated. Better cable on dac or transport?

If it doesn't make any difference and there's still return/refund policy, than you know what to do.
While most cabling rules are often not true, they are even less true when it comes to power cords...
For me I put the best power cable I have on my source which is a CDP. Also if you have a lot of components plugged into a power conditioner without a captive cord I'd put the best power cord you have on that conditioner.
I reaped significantly better result using best pc to transport on my transport/dac combo when playing with same cable brand~three levels apart. But that doesn't mean a thing, as pointed out, each system and preference are unique into its own, you will have to make that call on yours.
