I have two DACs on my desk: a Fosi Audio K7 and a Topping DX5 II. I originally tried stacking them for better cable management, but I got worried about heat. The DX5 II gets warm, and I didn’t want the K7 sitting on top of it and blocking heat dissipation, so I moved them side-by-side instead.

Now I’m trying to clean up the cables. What I want to do is zip-tie the AC power cable and the USB cable together for each DAC so that each one has basically a single, neat “combined” cable running out the back.

My question is: Is there any problem doing this? Could it cause noise, hum, hiss, ground loop issues, EMI, or anything else if the USB cable is bundled tightly against the AC power cable? I tried searching everywhere but couldn’t find anyone who talked about this specifically.

If anyone has experience doing this with DACs, I’d love to know if it’s safe or if I should keep the cables separated.

Thanks in advance!
