Odd that this discussion comes up now. My wife made her way to the basement workshop last night and sat in the listening chair while I was playing the Kind Of Blue Deluxe 50th Anniversary Collector's Edition and the first thing she asked was if all four pairs were playing, when in fact the only ones playing were the 250ti on the ends. Then she commented on how distinct each individual instrument was and how everything was placed so well across the room. She doesn't know the term "soundstage" but she certainly gets it. Not sure why it would take a 2-way with a wave-guide to improve this but I'm pretty pleased with the way the massive 4-way pyramid does it—without a modern wave-guide. At one point I toyed with getting a 1400 Array. Maybe that needs to be my next acquisition just to see what it can do. At the time I got sidetracked by the 4345 for the same money.
