ive had both, but not at the same time. These are going to sound very different from each other. Im a huge fan of full range speakers, Zu and Tekton, so it was easy for me to sell my 685's and move on. IMO there is no contest between the lores and 685's for my tastes, they image and punch much better. The good news is its pretty easy to sell a par of 685's and the Tektons come with a pretty good return policy if you dont like them, you wouldnt be out much.
