That's a pretty good summation of the two....I agree almost completely.
I don't get the fatigue factor from the Cirrus models that you describe, but I can see where it would be that way for others. I've owned both, and I currently have the 5.5....and it is my preference, although I could be happy with either one.
I didn't get the fatigue factor with my B&W C5, because they are not as neutral as the Q701. It appeared only with the Q701 or atleast it wasn't really a problem with the C5.
As i said, there's nothing wrong with the Cirrus, just not my main choice. If I do critical listening sessions I do them with my home setup.
