You just picked the three best measuring dac's to do a measurement comparison. :) I've seen measurements of the CEC and BMC equipment and they are not the best in the world like your examples but they are at least excellent. Over a certain threshold measurements have less importance than build quality, long term reliability (my CEC HD53N volume control was wonky and the warranty short), long term support, looks, perceived value and resale price.
I just snagged a few recent examples that were vaguely in the same class as the DirectStream. Not trying to bash PS Audio, just using it as a case study in how marketing and expectations can differ from real-world results.
I agree that measurements don't tell the whole story - however, when Ted Smith of PS Audio goes on and on about jitter (page 1 of that review, about half way down) and the measurements show issues with that very thing.... I'm trying to tie this in to your earlier comment about the Schiit stack versus the UltraDAC. The Schiit is highly anticipated but we don't really have any idea what it will deliver. And frankly, we don't know with the UltraDAC either. So let's keep an open mind until they arrive.
