I am a little curious about your question. When you say guide, I am not able to understand what is that you want? You want us to say 'yes' to the combination?
Both the Yamaha 663 and the Wharfedale 9.5 are good products. But whether you will like it or not depends upon your ears and liking. Logically you should audition the two with your own music and DVDs. If you like the sound, go ahead and pick them up.
Cheers
