Burn-in log #2. Stardate, well, you can see the date.
I'm at 75 hours. The 3-6 kHz region is becoming pronounced to the point that they're getting a little harsh with some material at higher volumes, but this is actually a good sign to me -- it says that things are changing. The bass is slightly tightening up and becoming less mushy. Lack of treble sparkle has not changed.
Does this sound in line with what some of you have experienced at 50--100 hours? Of course, I could just be full of sh*t, or maybe my ears are hearing a little differently today.
