The Ayre is now about $1400 more and used are getting near new price.
Check out Computeraudiophile.com for some comparisons and lot's of reviews of the w4s. There are some comments indicating the bass definition of the QB-9 leaves some wanting more, while the W4s seems to have exemplary bass definition and presence. I have a high regard for Ayre but am leaning now towards the W4s. I will likely listen to the Ayre again now that I have my new GM EOS speakers.
