is this combination ok?

Hello. Dont judge me for stupid question, im new with allo products :slight_smile: Im planning to listen music from external HDD via Volumio. So i combinated this setup: Sparky SBC + Kali + piano 2.1 + Wifi dongle. Is this setup ok? Or i need something else?

Good combination, you just need a 5V power supply that will provide at least 2.5 amps.

Do i need two PSU? For sparky and piano? Somewhere i read that linear PSU makes big impact in sound quality. Is this true?
Sorry for english :confused:

I’m using pi+ same combination as you. In my case only one PSU, pi gets power from Kali/Piano. I use the PSU supplied by Allo and very satisfied with the sound using “dual mono” mode.
Have not experimented with better PSU, might deliver even better sound.

WABE thanks for your answer.

Maybe somenone knows Rpi or Sparky is better in sound quality for kali + piano combination?
