Some of us actually feel that the older Maggies, while more restricted in dynamic range, had a more musical and pleasing midrange. Once you found the sweet spot, it was magic. I'm not specifically comparing the 3.5 vs 3.6, but the older designs to the newer ones. I am not a big fan of the latest QR models. They improved dynamics but sound much more "hi-fi" in my opinion. Personally, I would try and snatch up a pair of 3.5's at a sizable discount over the 3.6's.
