Does the 851N support Gapless Playback?

Gapless playback is the uninterrupted playback of consecutive audio tracks. This means relative time distances in the original audio source are preserved over track boundaries on playback.

The 851N supports gapless playback across all format types, but the files will need to be gapless and be streaming from a NAS/UPNP server that also supports gapless playback.
