I have to say that I’m finding that Roon doing the decoding and the Project S2 doing just rendering is much better over the S2 doing both. I find the soundstage has more depth and height than before. If you think about it, using my NUC i5 to do the decode rather than the xmos chip in the DAC make sense, it has more processing power. I did try listening with Roon just doing the decode. I feel it’s better than doing the pass through and the S2 doing everything, but not as good as the S2 rendering.
