So after 24 hours of playing one can hear them start to settle in. They sounded great right out of the box and so far I have only moved them around a little bit and I am letting them play. I have no idea how far I can take them but if this was it they would still be a really great pair of speakers. I expect by Tuesday when I am back in the store that they will have gotten most of the break in done and the rest will happen slowly over time. I am not a believer that things can't be good after 12-24 hours and in fact the 500 hour thing I don't buy 500 hours for many people this is months of use.
For now they are on the factory setting and I pumping different types of music through them.
