Gosh, this iDSD micro is just in a word "LISTENABLE!" It is non-fatiguing, and leads to those two and three hour listening sessions where you wonder where the hell all the time went!!
But don't mistake the above as meaning non-detailed. While it may not be 'hyper-detailed' I never once feel any lack of actual information. I think another good word is "BALANCE." All just seems to be in its proper place. Instruments sound natural. Full bodied, rich, AND detailed and nuanced.
Also, if you are into DSD, or have a lot of DSD recordings/SACD rips like I do, a DAC that does native DSD conversion is a MUST. In my opinion you haven't really heard DSD until you have heard it on a DAC like the iFi iDSD Micro. (or Nano for that matter)
I am currently enjoying Valerie Gergiev conducting the LSO in a beautiful performance of Debussy's La Mer. This is a native DSD64 recording with minimal or no PCM editing. And it sounds like I am sitting first row center balcony in the concert hall.
