I had the rose rs250 for a year and dmp a6 for 3 months. The problems with Hifirose rs250 is:
1) overpriced
2) rose connect app sucks
3) no tidal connect and no plan in the future to developp it.
The good thing:
1)youtube built-in App
2) hdmi output to display cover art on a monitor.
I prefer a lot the eversolo. The app is very stable . I simply bought a 40$ chromecast to miror my tablet screen for the album cover art on my monitor. Save your money for the streamer and spend more on the dac.
