Two days, ago, I received my new uDac, and I am thoroughly enchanted. This being my first foray into the world of audiophilia, I wasn't quite sure what a dramatic increase in sound quality would, well, sound like . . . nevertheless, through only a pair of Klipsch Image S4s (and my MacBook Pro), I've experienced a decided aural boost in clarity -- especially where my lossless files are concerned.
(I begin, now, to understand what one recently-read reviewer said concerning hearing the "air between the notes.")
I'm already saving money for an HDP.

PS: In addition, excellent design. Good feel. Nice heft.
