Rio Karma
The Rio Karma is a portable HD based player by RioAudio.
It features 20GB capacity, FLAC, MP3, Ogg Vorbis and WMA playback. As of now, it is the only DAP capable of perfect gapless MP3 playback. It also features excellent sound quality, Parametric Equalizer, an intuitive user interface, about 15 hours of battery life and other advanced features not found on any other DAP. However, Rio Audio seems to have discontinued the Karma as it is no longer sold by major retailers and Rio Audio's site itself.
