Good budget choices going with the NAD gear. I have heard various Mission speakers models about 5 years ago and I was not the least bit impressed with them. The Mission speakers had some kind of very audible cycling up and down when no music was playing on them and also while music was playing on them too. It was a constant changing tone from tweeter to woofer and then back to the tweeter, and so on. Very weird.

Must you have floor standers or would large bookshelf speakers be an option?
