High quality power conditioner and cables to all your components is worth the effort. Minor upgrade to one component is of questionable use. Judging by your post, I’m guessing that you are saying that you want components of quality similar to your Aurender, but it would sure be useful to see what else is in the room via your system posted on your profile. Perhaps, there are better place to put your upgrade money.
Cables for Aurender N150
I’ve had my Aurender N150 for 6 months and have been using an AudioQuest Carbon USB cable and a Shunyata Taipan power cable that I had available. I’ve really enjoyed the N150. Have Aurender owners found benefit in going farther upscale for USB and power cables?
For the non-Aurender people out there, the N150 is the current bottom of Aurender models . I’ve had excellent success when upgrading other components’ cables but you can hit that point where you don’t need Ferrari tires on a Honda.
