I have one and just sent in the request for a RMA to the dealer to return it just a few days before the 30 day limit.
I compared to the Holo Audio Red and Lumin U2 Mini for many hours and what I found was the Eversolo is actually missing information in the music. Where there are layered vocals with echos in the background those echos are missing but they are completely well defined and heard with the Holo Red and Lumin.
I also found the Eversolo was not a good synergy with some DACs depending on connection type and in some cases sounds very harsh.
I have many other streamers: Aurender A1000, Lumin U1, Lumin U2, Denafrips Arce and Arcas, and they all provide more details in the music and a more pleasant listening experience.
If I could recommend just one streamer best bang for the buck get the Holo Audio Red.
If you want a gizmo to play with that has lots of bells and whistles get the Eversolo.
