Ah, then it is a mystery unless somehow the USB interface improves jitter a little each time. It cannot improve other types of distortion can it?
Now regarding a later in the thread comment, how could you hear a preference for one regardless of which it was and not also be able to hear one matching or not matching the reference? If one sounds preferable to the reference and one doesn't you know which is the reference.
