Hi Jond,
800 hours? Well you’ll be the recipient of a thoroughly burned in power cable 😊. I get the preamp "heart of the system" idea but I’d try it on both the preamp and your tube Audio Note DAC. Most DACs are generally quite responsive to better power cables. Curious to know where the cable will have the greater impact in your fine audio system.
