Marc, the '7701 isn't out yet, so I don't think anyone can answer your questions. Apex announced the '7701 many months ago, and J&R Music World has had it on back-order for months (pre-order only; they've never had it in stock), so I seriously wonder if the player will ever be released. I wonder if Apex is having licensing issues with Sony and Philips and/or Meridian to incorporate the new audio formats.
The reason being in the latest Sound and Vision magazine it's posted in the J&R ad. I called them. They said it should be coming in within a couple weeks.
