I must say that whether or not burn in has anything to do with it, I like the sound of my 950/770 much better after a week or two of tweaking. Right out of the box I was not very happy. I thought about all of those months of waiting...then I got out my spl meter, adjusted the crossovers, and just listened. Maybe it was the tweaking...maybe it was my fairly new speakers...maybe it was just me. I love the sound I get today!
