Jebsmith73, yea, the first 3 hrs of listening is a high pitch squelch beyound belief, I threw my head phones off my head, I thought my ears were fricken bleeding from the brightness!, all that goes away quite quikly, I still do not have 400 hrs, 700 hrs is said to me to be the magic number, I believe 500 should get most?, Jeb, I will not have the other GTX-D Rhodium until monday or tuesday, to be honest here, I hate burning in the outlet's, only one other item in my system took this long for burn-in, my digital player, that's it, The fricken krell only took 500 hrs, LOL.
