I've had my Kann Cube for a couple of weeks. I initially had a long list of things I didn't like. My opinion is changing.
At first, the Kann Cube seemed ruthlessly unforgiving of poor recordings but now it does not. It isn't just about rediscovering the music I love, it is about discovering music I did not appreciate before.
I thought I was buying a player for acoustic and classical. Last night, I was listening to King Crimson Volkshaus Zurich Switzerland, 1995-05-06 (2cd) and heard detail in the electric guitar distortion that amazed me. I stayed up too late last night listening to every note. Zero ear fatigue; slept like a baby; couldn't wait to listen again.
I've transitioned to running the amp in hi-gain mode with the volume lower and I hear even more detail. The Kann Cube warns that doing so will drain the battery quickly but I don't care because I like what I hear. One hour of 16bit flac music used 10% battery.
I found a $32 silicon case,

I have not heard the DX220.
