I stopped by Audio 46 in Manhattan this morning. I was hoping to demo the IER Z1R and Legend X but neither were in stock so I settled for the Empire Ears Phantom and Noble Kahn. Both were notable for their resolution and clarity-- and the Kahn for its forward midrange-- however neither (imho) could top the Solaris' rich and open soundstage, balanced tonality and, as @fzman aptly puts it, its natural instrumental timber. I also gave the Atlas another whirl and am still satisfied that the Solaris contains the perfect amount of bass for my tastes, which leads me wondering if the Legend X might be too much after all. The Solaris is still king, however the Z1R looms ominously out there somewhere. Perhaps the universe is just urging me to be happy with what I have (which is a lot).
