By the way, I posted these impressions yesterday in the "old" Speaka thread before being alerted to this one.

I have purchased a DragonFly Black and Xtremepro X1-1 (identical to Speaka) in the last week, and I FAR prefer the Xtremepro X1 in A/B audio testing with the identical rig -- a PC with Klipsch ProMedia 2.1 THX satellites and sub, 320 kbps MP3 streaming through Google Play Music. Better tonal control, better separation, far less shrill in the highs, less muddy bass, far better volume control. I was pretty damn disappointed in the DF Black, to be honest.
The Xtremepro X1-1 is better in everything, basically, and it's $65 cheaper. A true find and a real steal.
Still deciding whether I want to stick with the Xtremepro X1-1 or go with the Apple headphone dongle DAC since the above poster mentioned the Xtremepro X1-1 won't work with iOS because it requires too much power, much like the original Dragonfly. Would be nice to have an all-in-one solution for my iPhone and my office laptop audio, and I haven't purchased an Apple Camera Connector USB 3 yet to test on my iPhone.
