I finally received my unit at the end of September - about 6 weeks after the order was placed. Again I was too busy with work to write about it - I gotta change jobs or something.
It's got about 20 hours burn-in time. I'm impressed with how much more of a soundstage and depth it casts. It also renders the bass with more girth without muddying up the bottom - I no longer think that my KEF R300 bookshelfs are bass shy. Cymbals, triangles, and acoustic guitars are rendered realistically - which is generally true for most acoustic instruments. The vocals are slightly improved - I don't know how to qualify this.
Occasionally when the music is too busy like when the instruments are all mostly centered, fast, and competing with each other volume wise, the rendering sounds disorienting like the signals are out of phase which I liken to a bad attempt at creating surround sound from 2 channels. This rarely happens but is more pronounced compared to my cheaper Dac-Wow.
Overall, worth the price and wait.
