Interesting little device. I had never heard of it before. It does the same thing as the TotalDac reclocker but at much lower price point. While USB has its issues, few other connections can offer the high resolution playback that USB can. Most AES/EBU today is limited to single DSD and 24/192 while USB can go as high as 4x DSD and 32/384 although many, including myself, would suggest that single DSD and 24/192 is more than adequate. As you review the specs of this device, you will find that it has its limitations, at least on paper. While specs don't frequently tell you how good something sounds, this unit actually boasts about having a sensational dynamic range of 105 dB. While that is a very good dynamic range, it would serve as a chokehold for even the d1-dual which has a DR that approaches 160 dB. Still, if you decide to get one and you find it to be fantastic, please let us know.
