The first track on this album is "The Robots." There are dueling bass lines early in the song, an excellent test of the speakers' low-frequency response and resolving power in this range. Every track on the album has plenty of deep bass, sizzling high-frequency sounds, rather complex arrangements, and a host of other sonic traits. And it is also an excellent album to listen to when I'm not reviewing speakers. I think it's an outstanding album, from start to finish. My first sonic impressions of the Børresen X2s were very, very good. I was impressed with the vast soundstage that surrounded the speakers, and their very good center-fill. On most material, including the Kraftwerk album, the X2's center-fill was superb, it created sharply outlined images in their surprisingly vast soundstage, reminding me of speakers that cost much, much more.
