I played the "Ride" again at my place this morning. We were listening at about 84dB at Marks. I cranked it up to around 90dB today. At 90, I started to hear a little bit of the high end harshness, and as we saw before it started to go away as I lowered the volume. So, there is still some harshness at the upper ends, but not to the extreme we heard it at Marks. Is this the room dynamics, other components, cables, speaker break in...I'll leave that for the rest of you to debate.
