Using a Raspberry Pi3 with a HiFiBerry clone and Volumio with FLAC files over an NAS.
I've been using a standard 5V 2.4A "wall wart" power supply. Sound quality seemed reasonable.
Tried an external battery. Sound is cleaner, but seems a little flat andc harsh compared to the power supply
Purchased a iFi Audio iPower 5V power adapter for around $50. Sound quality is better in every way imaginable. Listened to system for several days and there was no denying the difference. I had no idea how much the power supply noise was adversely affecting the sound quality until it was gone.
Tried to watch a movie using Kodi. The movie sound was also better. I could even hear dialogue more clearly. Shortly after starting the movie I started getting a lighting bolt (low power). Unplugged the external USB hard drive and watched something over the network. Working fine. The next day I tried to watch something over the network again and got the lightening bolt right away. What the !?#@%? Switched back to $6 power supply. No lightening bolt. Even able to plug an the external hard drive just like I always have before. Lightening bolt with the IFI power supply. Even tried a different Raspberry PI. Power supply being returned.
Ordered a 5V 2.1A linear power supply from China for around $70. Will post results.
Are there any other power sources that I should consider that don't cost hundreds of dollars?
