The DNP-720AE has been hanging around at trade shows for a while, but it's only just been tagged up with a price. And boy, what a price: £429 ($660) for a stereo box that snatches AirPlay, DLNA, Internet radio, Napster and off your WiFi or wired network and outputs to your amp. Sure, it packs a decent 24-bit DAC and will no doubt deliver that sweet Denon sound when added to your stack -- but if you don't already own a bunch of same-brand components then there's plenty of alternatives to consider.
