Apogee Groove - Portable USB DAC and headphone amp for Mac and PC

Apogee Electronics, industry leader in digital audio recording technology since 1985, is pleased to introduce Apogee Groove™ – a new portable USB DAC and headphone amp for listening to music on your Mac or PC. Built upon Apogee’s 30-year history of award-winning digital audio technology for music creation, Groove unlocks the highest possible quality of any headphones or powered speakers you have, allowing you to listen to the music you love with incredible lifelike clarity. 

Apogee’s digital audio technology has been trusted by professional recording artists, producers and engineers from around the world to create countless GRAMMY® and OSCAR® winning recordings since 1985. For the first time, Groove puts this same technology into a compact, durable, easy to use interface for consumers, providing a music listening experience of unparalleled quality, as it was originally captured in the recording studio.  

Groove’s Unique Circuit Design
Constant Current Drive™
Groove’s Constant Current Drive output stage is a truly revolutionary approach to dealing with the wide impedance variations of headphones available on the market today. With Constant Current Drive topology, Groove’s output stage’s voltage is dynamically “molded” to the impedance variations of the connected headphones, thereby smoothing out frequency response non-linearity that occurs with traditional headphone outputs. 

Quad Sum DAC™
Groove also features a Quad Sum DAC design which employs four digital-to-analog converters per channel to achieve the highest  dynamic range and lowest distortion (THD+N) of any device in its class.
