I just received my 005 from Jason at Midwest Audio. He is a great guy, highly responsive, earnest and knowledgeable. I highly recommend him. He sent me a letter thanking me for my business and included a battery for the remote, which the manufacturer oddly doesn't include.
Given all the rave review by real users here and on head fi, I thought I'd give one a shot.
While I've only got a few hours on it, and haven't played much with the DPLL settings, all I can say is holy cow, this DAC is spectacular. I concur with what everyone is saying about it. It is extremely accurate and detailed, yet extremely natural and non-fatiguing. I find myself being happily immersed in the music and able to shift my focus between musicians and vocalists even during complex passages.
What has stood out thus far is the presentation of details I've never heard before on familiar recordings as well as the extremely natural sounds of wood and steel strings when listening to acoustic guitar. For example, the subtle interplay between Julian Lage and Chris Eldridge on For Critter and Cattle in the Cane (Alternative Take) from Close to Picture is evident as they play off each other and exchange lead and rhythm duties. I've never quite heard Chris tease his strings with strokes that move slightly up and down the strings, bringing out a zingy and slightly percussive quality. I thought to myself, I'm glad Chris is playing new strings! That's how much information is presented.
Listening to I'm With Her play Hannah Hunt allows me to easily distinguish between the voices of Aoife, Sarah and Sara, which can be difficult to do on even a spectacular system.
In any event, I could go on. But, if your system is resolving enough, this DAC will not disappoint. It's early in my relationship with it but I will say I am frankly quite astonished at what it brings to my system.
