[I auudtioned them just briefly in Denver and was astonished by their clarity.  Question - do they ever tend toward over-brightness?]
Just out of curiosity, does Jim routinely provide the treble contour circuit, or is that a special order item?  The HT3 is voiced flat, while most commercial speakers I've heard and measured were hotter in the highs.  Still, you can never tell how a speaker will interact with the room or some program material.  If you don't have the contour circuit, the highs can be brought down easily with a single resistor, but then you would be pretty much stuck with that setting.  I like it the way it is.  In any event, I doubt that cables, wires, interconnects will affect anything.  But then I always say that.  it's all about crossovers.
