No side by side comparisons yet, but other speakers I've owned include Paradigm Reference Active 20 monitors, ESS AMT 1D with the Heil air motion transformer and Omega Grande 6 to name a few of the more recent ones. These compare quite favorably. I loved the Heil tweeter/midrange unit of the ESS speakers, but the bass was a bit loose and wooly. The Omega was awesome on female vocals, but not as dynamic as I'm used to. And the paradigm was fantastic at imaging and soundstage, and probably my favorite speaker up until the Daber's. The Monitor 3 imaging and soundstage is on par with the Paradigms, but with a little deeper low end, and overall better midrange purity. I'm a big fan of Orthodynamic/Isodynamic headphones, and the tweeter definitely has some of that signature I love. Dispersion is fantastic. The aluminum domed mids are what I think really give the speakers the edge over a good two way design, without sacrificing imaging, and they allow the woofer to be freed up from high mid reproduction.
