I agree with the KEF recommendations and I have the classic Reference 105’s which have pretty impressive imaging, however, my Canton Ergo Passiv set is absolutely incredible for imaging. BUT….The most impressive soundstage and depth of field I’ve owned we’re the Polk SDA series 1’s, 2’s, and CRA’s. They have a connecting cable between the two speakers that eliminates cross-phasing and creates a 3D image and extremely wide and deep soundstage. The criticism is that they don’t produce the most critically accurate frequency graphs but they are REALLY fun to listen to. I wish I had never sold them.
