Lauscher,
The HD3 tone is very smooth, natural and would say that they may be a click to the left of neutral without sacrificing detail. This HD3 cable is full sounding with great extension and bass weight and has a presence like any of the cables I mentioned. The Audience "e" is right behind it especially if using tubes since tube equipment can be rich and the "e" cord would be a good compromise with its thinner/slightly more resolving sound.
I wouldn't bother with the Shunyata cables, I found them to be one dimensional as if I were listening through a tunnel with the weakest bass I've heard. By far my worst experience with cables in my audiophilia career....
