Synergistic Research Euphoria HC power cord.

don't use any cables that are ofc junk they're extremely overpriced and you're being ripped off if you want the best sound used cables that are made from OCC single Crystal copper or silver far superior to anything ofc on the market at any price night especially rip off Transparent and MIT.

I had the N05XD which was a streamer/DAC/Pre-amp.  No interconnects needed.  I swapped it out for a Reimyo 777 DAC, SPL Director Preamp and Lumin U2mini streamer. Then traded the XA25 for the SPL S1200.  My system is now very accurate but the 777 made it holographic. I have to down sample all music to CD quality as the 777 doesn't not do any over sampling or hi-res music

I have the L3 Atmosphere X HC power cable on my Gryphon Diablo 300 integrated and other SR power cables employed thorough out the system.  I really appreciate the performance.  I have used upper level Audience, AQ, and MIT in my systems over the years.  Each has its advantages and can be very system dependent. The Cable Company has provided solid advice in the past due to their extensive personal knowledge or database of products in certain applications acquired over time due to their business model of lending...  I used to like to mix a lot of different brand cables in my system but the last years I have relaxed into more of a "full system same company" approach.  It works well with my current SR products.  You may want to think more about the Audioquest options that might work well with your other AQ cables.  Good luck.

I have tried so many power cords. I did own for a time the SR SX power cord. It was good, but, when I demoed a AudioQuest Dragon it was game over. (BTW, I also own the Lumin X1).

This power cord really locked in with my equipment. I have now bought several, all used of course.

So, you can go the continuous upgrade path or seek out a Used Dragon and be done.
