Eversolo /Zidoo. My Dad's A6 streamers USB quit working after their latest firmware. Denied there were any problems... but at the same time others are having issues with USB.
I asked them for the last firmware, they said no that's dangerous. So after them insisting there were no FW problems, I let them know there were only 5 days left on the warranty, could I please send it in. Silence, they totally ignored my request for warranty service. That was 6/22.
I thought it was a decent streamer but unfortunately I can no longer recommend Eversolo.
