Default Gap/gapless tests on firmware 1.01.29

I encoded Pink Floyd's gapless "Dark Side of the Moon" album to WAV (44kHz 16bit stereo), MP3 (LAME 3.97 -v0 --vbr-new), Ogg Vorbis (aoTuV b5.5 -q6).

I played the album in all 3 formats and recorded the track transitions to my computer, then I checked how big the gaps were.

WAV: ~0.4 sec
MP3: ~0.5 sec
Vorbis: ~0.9 sec

As usual, the de-facto gapless Ogg Vorbis format is the worst - I noticed the same on my Cowon X5 and D2. When will DAP manufacturers ever learn?

To make things even worse for gapless playback, the Sansa Clip fades the beginnings and ends of tracks for about 0.05 seconds, no matter what audio codec.
