*** You're right to argue that Gordon's wav/lossless "blind test" performed in an unknown manner on unknown subjects at a trade show (!) without statistical analysis of the "results" is not robust and that his listening tests are probably more valid. ***
You have hit the nail on the head - what Gordon described is not a statistically valid test. It wasn't "double blind" (which would imply neither the observer nor the experimenter knew what is being tested), and it wasn't ABX, simply AB, hence subject to all sorts of biases.
What I found amusing was the implication that *if* Gordon was right (that is, if differences between formats were audible and that CPU processing capacity was a factor) *then* it indicates that his products are not working effectively (because async USB is *supposed* to isolate such differences away from the DAC). Not sure he intended to convey that implication to his readers.
