I auditioned them this past weekend with near top VTL gear (S400, 6.5), DCS digital and mostly transparent cables.
Honestly, they sound like a Maxx III in a smaller package. They are noticably bigger in size and sound than the WP8s and my Sophia 2s, and I'd say they sound closer to the Maxx III and Alexandria II's than the WP8 or Sophia 2s.
Simply, they have a sense of "weight" in the midrange that the smaller WP8/Sophias can't touch. They also sound effortless and uncongested and natural. They are very, very coherent and balanced.
This will sound cheesy, but my first comment to the sales rep after the demo was "Every Wilson speaker sounds impressive, but these new Sashas are the first Wilson speaker to sound gorgeous."
The new Sashas are a bargain, I'm thinking about upgrading my Sophia 2s...
