Is your desktop computer faster, dissipate less heat, screen seem sharper and colors start popping out when you user expensive power cord? Try it. Streamer is just an ARM computer.
Comparing a multipurpose computer to a dedicated audio streamer is like comparing a Porsche to a Toyota Corolla — they’re both built to get you from A to B but do it very differently given their design and purpose, and that matters a lot. Everything in audio matters, including power cables on streamers. Go to any audio show or high-end dealer and none of them — none — use a stock power cable on their streamers.
