I swore off Eversolo products after my A6 would not recognize my high end Samsung SSD card. Their customer service actually wanted me to send them the SSD card so they could test it in China. I did not. The app was a bit buggy too, but better than Cambridge or Bluesound.
Summit HiFi offered to credit me the purchase price of the A6 towards an A8. I had a separate DAC so the A8 really did not work for me. I ended up selling the A6 to a friend that knew the SSD feature did not work. I ended up with an Innuos Pulse plus Phoenix USB replacing the A6. In the end I am glad the Eversolo customer service was so terrible. I ended up with an outstanding streamer with an easy to use app (Sense).
The A10 looks interesting, but not in my system.
