Autospec,
I see that you are selling those speaker cables. My suspicion is that a different pair of speaker cables and some more break-in time will be the ticket. You might even try a pair of Signal Cables. They're inexpensive, and worked well with those speakers. I've owned the 5.3's and the 6.2's, and neither had dull highs, except when paired with dulling cables.
Also, if you're not sure about break-in time, read the comments here and on Audio Review about those speakers. Anything less than 300-500 hours, and they just don't sound good.
Good luck,
Howard
