My Endgame DAP alrd here (hopefully).
Still on Burn in phase.
So far from 10 hour burn in, my impression, Hiss is consider Unnoticeable with Solaris.
Interestingly, found that in Mango Android is more darker background then Mango OS...
Unfortunately my AMP8 seems defect, producing High pitch noise, even when u stop the song...
Interested to see how it works out. By any chance have you had any experience with astell kern sp1000?
