Well, thanks for the clarification -- that does make a difference. From what I've heard, the VSi75 is significantly more "ARC" than the "entry level" I/50. So again, your first-hand experience and educated comments are very helpful. What model speakers were you listening through, btw?
At this point, I'm still torn about not being able to compare Levinson or Hegel to ARC in person. It would require a full-day air flight from here for me to hear any of those three.
