I have few headphones and I love magnetic planar ones. For years I enjoyed my He-560 V2 regardless of the few known flaws. Now I want to get something better and off course should be still planar. I would like to get something with better soundstage and neutral but still with warm sound not bassy but with the right amount of bass to enjoy few genres (he-560 have more bass then 400I I owned and that's why i like them and this excludes Sundara too). Price range? 500 - 700
