I fear people missed that Yello and even XLO are a joke. Yello is mood music for unboxing. XLO is a great test CD. But really the music used is way down the list and hardly relevant.
Speaker setup is first, put them where the tone, and bass response, are pleasant and smooth. It really does not matter what music is used, just so long as it has enough bass variety and enough vocals or instrumentals to be sure of getting a good midrange balance.
Next step uses a tape measure, no music required. Adjust the speakers to be precisely equidistant and with symmetrical toe in. Finally, listen to lots of music and make very small adjustments to toe. More toe in, deeper image, more precise imaging. Less toe in, wider stage, less precise imaging. When done, double check with the tape measure to be sure they are still perfectly equidistant and symmetrical.
That is it. Done. No special music required at any step in the process. The music you play should be, as always, music you enjoy.
