Great review! I had to agree that a Chord DAP would be a game changer. Chord if you are reading this... It's up to you

Well done Ejong. A really good review. You should be proud of what you've done here , well done for making the time to be a part of the Chord review team

Interesting review, sadly I don't own the Roxanne, but I own the Custom Art Harmony 8 Pro and the Etymotic ER-4 (modified with only 14 ohms left), with both IEMs I can easy detect any hiss on my source gear. I tried the same with Mojo but the first time ever I have no hiss, I'd set the volume to the maximum on Mojo and paused the music to test the hiss (I would be dead if I would play with this output power LOL), I know this is a unreal testing - but I want to try if I ever reach any hiss, because the same on low volume with zero hiss. It's the very first gear I own which has zero hiss, it's dead quiet silent like when the devices is powered off, very impressive, all other gear I have has at least on highest volume levels always louder or quieter hiss.
