Summary: The good: Initial setup was nice. The onscreen GUI made it simple. The front panel display kept me apprised of the firmware upgrade process. Really nice device. The bad: The HDMI switch doesn't work reliably. I have two displays and tried two different sources. That's four combinations of sources and displays, with two "sets" of unique cabling. No combination worked reliably. I sent an email to Marantz. Six hours later*, no response. I called.
