I go now times less on the contents of the CD, this was not written enough, and a must for all understand what the music. Who wants to test whether his HIFI and speakers which are good or wants to establish something new, you should buy this CD and thus go to the HiFi shop and test his equipment so desire. The sound images and their bandwidth with spatial resolution are that demand everything from the HiFi system and speakers. One of the best TEST CDs I've heard so far. Which does not mean that you should buy them only as a test CD :-), it is a pleasure to hear.
