Audirvana is an audiophile player for Mac OSX.

No equalizer, no trendy special effects, just the music

• Native playing of FLAC, libSndFile (WAV, AIFF, ...), ALAC and other quicktime formats (AAC, MP3, ...)
• Direct sound path, directly to the CoreAudio HAL for pure bit perfect sound
• Audio Device exclusive access mode
• HAL I/O using DAC native physical formats "Integer Mode" (instead of CoreAudio 32bit float)
• Automatic sample rate switching
• Up/Oversampling capability
• Plays completely from memory
• Tracks are loaded, decoded and sample rate converted in a memory buffer before being played
• Minimizing CPU and hard drive activity to lessen sources of interference
• Gapless playback by using a double buffering mechanism (playing track and next track)
• Transparent split load for loading tracks of any size
• Background tracks loading/decoding (including sample rate conversion)
• Playlist (m3u & m3u8 formats) load/save
• Handles Apple IR Remote
• Automated updates downloading (using Sparkle)

Currently works on 10.6 & 10.7 Intel Macs with any CoreAudio compatible DAC
