Thanks. I have been wrestling with this for more than a year, when I decided I was going to put my cd collection on to a computer. Most laptops do not have sp/dif out but do have hdmi. I couldn’t understand why dac’s do not support hdmi input. I contacted simaudio (I have a moon 100d) and they gave me the same advice as you. But I thought then as now, why purchase a usb to sp/dif converter when the laptops hd graphics 4000 controller has already done the job? Two months ago I bought a Toshiba all solid state Ultrabook and MC, based on recent TAS articles on computer audio. I came close to buying a Stello usb converter which would cost $500 but then based on the TAS issue 233 review of the Bryston bda-2 (page 86) I bought a KanexPro de-embedder for $65.00. The TAS reviewer had great experience (although almost embarrassed to admit it) with a de-embedder and I too use an Oppo DVD player front end so I figured I had nothing to lose. I plan to use it with both the Oppo (converting sacd to pcm is intriguing) and the ultrabook. An audio de-embedder comes from the world of pro a/v and the world of hi-fi is often ignorant of (or prejudiced against) the stellar products out there.
