Note, Louis's drivers aren't off-the-shelf and compare favorably with the absolute best available. Unless you were experimenting with Lowther, Voxativ, and other world class "full range" drivers I still think you owe it to yourself to at least give the 3i a try. I still think you'd be surprised. The RS5 drivers ARE that good. I didn't enjoy my KEF LS50's so much after trying the 3xrs. I know they're very different, but that was also part of the appeal. The KEF's sound thin and sterile unless you juice them with power to get their diaphragms moving....which was too loud for me and my room. The RS5's light up without the need to be cranked. They're also faster, more resolving, more pure, and image better than the KEFs.
