As good as they are,I'm not sure I'd sink $1500 into a pair if 105/3s, when you can easily find 107s & 107/2s in very nice condition for $800-$1000. I'm a long time 107/2 owner, so I may be biased, but I don't think there is another dynamic speaker that can touch a 107 for less than twice that price! Almost any of those KEFs that are more than 10 years old are going to need new woofer surrounds, but that shouldn't scare you off. A surround set for 107s cost less than $100, and they are not hard to do your self.
