Personally I didn't enjoy the detailed but flat sound signature of the K550 (ok, I just had a few minutes with them in a store recently). To repeat myself, I am very pleased with the performance of the K167. Even in genres where you usually do not have a lot of bass; then they present mids and highs in audiophile quality with a good representation of a wide sound stage.
In general, I come to the conclusion, that the K167 really shine with good quality recordings on flac & co. 320kbit mp3s are also nice but the same tracks played in flac are just no comparison on the K167.
Here's a track with very little bass: http://rapidgator.net/file/61438089/01._Joanna_Newsom_-_Emily.flac.html
Please give it a try and I'm curious what you think when you play it with the Tiesto's.
