Although I had not tried to configure the Node 2 to do gapless playback, I did not know if it would or not. Here is the "official word" from Bluesound below...
Here at Bluesound, we are an alliance of audiophiles with the mission to create innovative wireless digital audio products and technologies, that allow for the most true-to-life music experience possible. Bluesound Players offer gapless playback by default for all supported file types (BLS-KB13-X01).
There is no feature to manually configure options for gapless playback or cross fade between tracks.
Hope this helps. BTW I have many different file types in my personal audio library. So far, the Node 2 has played them all without any problems or glitches. It's nice to be able to have over 14,000 tracks available to me on an Iphone as my remote controller.
