I challenge anyone to pick a pair that gets the 16-18KHz sizzle of an open hi-hat sounding so natural, soft and yet incredibly alive and perfectly audible. This is of course my own taste (some prefer warmer cans), but everything above 5KHz is really important to me and the music I enjoy (everything electronic and not very commercial-sounding; classical; ambient). I can't go as far as recommending an amp model, but something warmer could probably even out the highs - if that's your thing. However, there is absolutely nothing brittle here all the way into 18KHz territory - which is hugely impressive. The most transparent and crystal-clear highs I've ever heard for the price. If you can tolerate the slightly diffuse mid-range (which is solved by purchasing an amp), definitely get these!
