I did, and I do notice a difference. I liked the recordings that I made with the CA-11's but they didn't handle the low end as well as I would have liked. If you click on the link in my signature you can listen to some shows that I've recorded with the CA-11's and CA-14's. All of the shows from 2009 are with the CA-14's, as well as the Robert Randolph and On The One shows in November.
