When I owned the Studio 100s I was auditioning the S3s at home over a weekend when this offer popped up. Being able to compare all three at home was way more insightful than auditioning in the store. I found that Paradigm has a house sound that I spent time and money trying to overcome. Within the first few minutes even my family could easily hear the difference as well as that house sound.
The Paradigm's were more dynamic with more highs, mids, and lows which is what sold me in the first place. The reason these new speakers seemed sleepy was because I couldn't hear that stark differentiation of those highs, mids, and lows. They were simply making music. During my time with all three of the Paradigm's I'd listen to an album or two and become board. What the other speakers revealed was not boredom but a fatigue from being able to clearly differentiate the drivers from the listening position. I have to put my ear very close to the other speakers drivers just to hear they're working. In all, a difficult lesson finally learned.
Years later I briefly heard an all Audio Research system driving Paradigm Persona 9Fs at a store. Clearly the best Paradigm's so far, meh.
