Similar experience here with the 2Ce Sig IIs...they sounded ok, but not great, until set up correctly and with good amplification. Now, along with a pair of Vandy subs, they live up to their reviews in the stereo press. I would also say that to my ears, the sound of the 2C has evolved fairly dramatically over the years, becoming much more forward in the midrange and more detailed in the upper frequencies (while not becoming harsh or glaring), and tighter in the 100-200Hz range. The earlier versions, especially the 2Ci and its predecessors, are significantly more laid back and less impactful.
