There aren't many mail order dealers I'm aware of, but you can try http://www.referenceaudiovideo.com/. They're the only online authorized dealer I know.
You may want to consider buying them from a local dealer that will let you demo them for a month in your home. Are you near one? Also, if you must buy online, make sure Kef will warranty them. Just curious, which model are you looking for?
I live in Baltimore, and the closest KEF dealer is about 45 minutes away. It's not too far away but their a small store with very high prices and little inventory. There are only three KEF dealers in all of Maryland. I was hoping to find a better deal on-line.
I am looking for the Ci 130DS di-pole/bi-pole in-walls for my rear surround. I have an older pair of KEF Q90's as my front speakers that I bought a few years back when one of the high end shops near my house carried them, they don't anymore though. I have been using a small pair of Polk's for surround and figured it was time to move up.
