Having owned both the 7520 and HP50, I'd encourage you to trythe 7520. It is easy to drive from an ipod and does have a wow factor. The same can be said for the HP50...but the looks of it are odd. I think the 7520 is a better fit for those genres though. I haven't heard the P7...but if I really cared about looks, I'd try it. From all the reviews, it should satisfy your needs.
