Ding ding ding! That's the criteria the video guy hauls out as the ultimate test of an audio system. The fact that McIntosh does that for you -- and I assume many others, here -- is about as good a refutation as one could hope for. The only reply the video guy could make is, "Well, you don't know what really good sound is like." To which the only answer is, "Go home."
