Boy, I get stuck in a bunch of meetings all morning, and I come back to a college seminar on balanced circuit topography. We've got some folks here getting into some good back-and-forth about balanced circuits, but I think there are some others hiding in between that want to debate other things - like how many people think they'll use Dolby Headphone, or how many possibilities come to mind for the second zone output now that there is a dedicated remote to control it. I thought I might offer an alternative venue - specifically this thread - that could let this debate continue in great and informative detail without running the risk of drowning out other discussions about the 990.
