There are a couple of problems I have with Cyan on the 1520 with the audio quality. The only way to achieve the good low end sound is to turn on "dolby audio leveling", for some reason when that is turned on, the low end has more thump and depth to it. The problem is with Dolby audio leveling is that when a song goes to just voice or acoustic, it gets super loud, and then when the drums kick in, there's noticeable volume reduction. It doesn't sound appealing at all. If they'd just fix this problem, I'd be happy. I think the mids and highs on Cyan sound better than on 8. But the lows suck!
