That it won’t take 100 plays to hear that beautiful reverb slightly panned off-center. Or the subtle laughter of the artist after recording the main vocal that is left in the song. Groove brings back the joy of listening to music by letting you hear it the way it was intended. Once you listen through Groove, music just won’t be the same without it.  Improve your headphones Thanks to Groove’s Constant Current Drive™, you’ll discover a new level of clarity while improving the frequency response of your headphones.

Mix with confidence With Groove’s Quad Sum DAC™ design, which employs four digital-to-analog converters per channel, you will hear “the truth.” Groove’s high dynamic range and low distortion put it in a class of its own.

Experience Lossless Audio To take full advantage of lossless audio you need a premium DAC. Groove gives you the ability to hear your favorite tunes in full 192kHz resolution.
