Have you already tried a blind test, were another person being in another room plays a track from a highend NAS or a regular NAS and you guess which NAS is used? To get a significant result, this experiment should be repeated at least 20 times for the same track. I'd be interested in the results of such a test.
Did somebody other do such a blind test?

I've tried two different NAS and also streamed from a PC and I observed no difference in sound quality. But I had not the chance to try a highend NAS yet.

The difference was pronounced so did not do 20 tests.

Please post back when you've tried a Melco type NAS as we all know the theory why there shouldn't be a difference.
