The Apogee Groove is the best portable USB DAC and headphone amp for listening to music on your Mac or PC. Groove takes the same high quality audio technology found in the world’s most prestigious recording studios and delivers it to your laptop. Connect Groove to your computer’s USB port and your headphones or powered speakers to Groove’s audio output. It’s that easy. Groove’s output provides ample power at any impedance and Apogee’s Constant Current Drive™ technology makes your headphones sound their best. You’ll be amazed by the difference in sound quality – the precise stereo image, punchy bass and stunningly clear high-hats.

Constant Current Drive

Groove’s Constant Current Drive output stage dynamically compensates for the nonlinearities – acoustic, mechanical or electrical – of any connected headphones, resulting in lower distortion and a more linear frequency response. Whether listening through earbuds or “hi-fi” headphones, you’ll discover a new level of fidelity, clarity and detail.

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.

ESS Sabre DAC Technology

ESS Sabre32 32-bit Hyperstream DAC with Time Domain Jitter Eliminator offers unequaled dynamic range, ultra low distortion, and unmatched audio clarity free from input jitter.
