I did use this one also a little at the show. I tested it also at home. It is good, but it is not exciting. Without Audyssey Pro you stay in a different world. During the show I used my Samsung Plasma ( 64 inch) as a screen. I can put the different parts of the Audyssey system to on and off. Wenn I do not use anything of Audussey anymore the party is over. Drive, speed, sublime focus, dynamics and resolution are lost for a very big part. With the XP-20 I had very good results in dynamics, focus, resolution and in a wide and deep stage. But now every part with the way I measure I can top all of it. I learned to use Audyssey from a highend perspective. Audyssey is focussed on a different way. Those results are good sometimes but never thrilling. The way they use it you still loose too much. This part I did improve a lot. Wenn you build a surround system you first start with the stereo part. From stereo you build to Multi channel. The reason is very simple. Wenn every part in stereo is right it is easier to get it right in Multi channel. I have a lot of music on bluray these days and I love it. But I still play the most in stereo.
