Thomas and Stereo stated in his review that the S300 and S400 shouldn't even be in the same series as they are so different, the S400 should be W400 for waveguide. I'm sure the op has researched but this would be something a bit different, a rather directional but not "shouty" sound. Also, the rest of the review had a great chart with responses from audiophile friends. Now the trick would be figuring out where he Tekton would fit into that.
