I wasn’t surprised to find that my receiver takes a second or so to sync up to a new digital audio stream; this is not an unusual flaw. I was surprised that Airport Express isn’t sending a continuous audio signal to the receiver when it’s active, and that iTunes sends each song in a playlist as a separate digital stream.
Net result? My Kenwood VR-407 loses the first second or so of every song unless I set iTunes’ crossfade option to at least four seconds. With that, the first song is still chopped, but as long as I don’t change tracks manually very often, the majority are ok.
This would be acceptable as a short-term workaround, even though I despise crossfade, except that the device isn’t terribly stable. Several times in the first hour, the audio stream simply locked up and had to be restarted.
Bottom line, until there are updates for both iTunes and Airport Express, it won’t get much use at my house. I could switch the connection to analog to avoid the crossfade, but that won’t do anything about the unstable connection.
