This is not a problem with "burn-in" but the limitations of USB power. That's why you see portable amps loaded with capacitors, so they can store enough power in reserve for those big transients. Adding a regular headphone amp into the chain will rectify that.
Just clarifying as a few people have said this doesn't go well with low impedance IEMs... this will work good as a DAC paired with my Pico Slim and JH16? Really like the build of this thing but some comments have been a little discouraging. Also if I use it with the slim will that "count" towards the burn in on the DF so I can then try HP out?
Edit: I'm also curious about how using it as line out is "low-current operation" as this guy says if you're just maxing out the volume to use it as a DAC. Here he is talking about the "digital" sound it has with HP out vs using it with an amp:
"I used the DragonFly as a DAC for an Ncore amplifier I patched together today. I think the device sounds better in this mode. I don't hear as much digital edge or sibilance. Mercman posted over an AA saying his DragonFly sounded better used as a signal source for an amplifier. If this device does in fact sound better in low-current operation, I suspect operating it at higher currents required by headphones causes an extra measure of jitter, among other things, given the several sources of psu voltage noise that current will cause or induce."
Can someone explain this to me please? Thank you.
