Doesn't sound like the dragonfly is supported by the Pandora.
Dragonfly is cost effective because you can't beat it for it's price. They use and need to pay for the async stremlength license, do a 64 position dig controlled analog V control that will be more accurate than a pot. It's also not 'buttons' but whatever controls the V on your source computer. Incorporates 2 dedicated clocks, has seperate regulation and has a real warranty.
I suspect that the Halide is better for a little more but it also doesn't drive headphones.
It looks like the Pandora uses a polar tantalum 330mf output coupling cap off a likely inverting TPA6110a2 so there will be some bass roll off with low impedance phones. I don't consider this a big deal or indicative on the overall sound but I think it should be noted. Of course, bass will now become undesirable, LOL
The Dragonfly is working just fine. And seriously, do NOT do that. Mind your own business. I'm new to the Pandora AND Linux so I don't know how to do everything myself and have to ask. Don't post it here to try and make me look like an idiot.
Edit: Misunderstanding. My apologies.
I haven't exprerienced a bass rolloff with any of my headphones, low impedance or otherwise. If anything the Pandora has better low extension than most of my devices.
