I've never been one to believe the "speaker break in" thing. Always called it placebo effect. But either my ears are adjusting to the Air or it is sounding better.
Also learned tonight, sub out does not work without ac adapter plugged in. It just hums and very low output.
I also learned that Ethernet over power line will not work with the Air. I even ordered different power line units thinking I had a bad one. They work....when the Air is running on battery, but the second I plug the Air into the wall, it causes the power line adapter to lose synch. For those not knowing what I'm talking about..
