Just wanted to say that I used to install home theaters & fancy audio setups and the B&W speakers are very, very nice.
As far as songs go, can't give you specifics on those particular songs (not familiar with most of them), but just have a good variety of styles and a variety of songs that you are very familiar with and already listen to. At least for me that biggest thing is listening to a song I am very familiar with, that way I know what it sounds like in different environments and on different systems. Then you will notice a lot more differences in detail. Just from playing around with different high end gear in the shop I was suprised to play music I was familiar and have listened to for a long time, only to find that there were still small details (imaging, etc..) that I never noticed before.
What will you be running them off of at home?
