I liked the fact that you can install it on a USB drive (that's exactly what I did). Tested in the free version playing DSD format. I set the volume in the Volumio program interface to 30%, on the amplifier the volume control was turned off for about 11 hours. Launched the DSD file. Volumio reproduced a sound similar to "white noise" at maximum volume. After that, on my acoustics, the high-frequency speakers + high-frequency filter capacitors + tubes in the preamplifier failed. I'm not sure about the lamps, maybe it's a coincidence. This happened when playing the DSD format in the free version, the volume control in the Volumio interface does not work and the DSD format is played at 100% volume, only instead of the music itself, a sound similar to "white noise" is played, but if you raise the volume to 100%, then already music is playing. This is, in part, my fault, because before that I used Foobar and there is the same problem. Then I signed up a Volumio test Premium account and everything is in order there, the sound is regulated. It took about 1 month to restore my audio path. It's a shame, but I didn't manage to listen to Volumio normally. It would probably not be bad to make a warning in the interface of the free Volumio before playing the DSD format.
