A portable DAC with a big sonic punch

No matter what music sources you listen to on your computer — iTunes®, Spotify®, YouTube®, or downloaded high-res audio files — the Apogee Groove can make them all sound their best.

Crafted with care for better sound

Renowned as an innovator and industry leader in digital audio recording, Apogee carefully builds each Groove right here in the USA to the same exacting standards as their studio gear, so you can count on your music sounding its best. The Groove's durable aluminum case comes packed with the highest-quality components, including an audiophile-grade ESS Sabre™ DAC with jitter-eliminating circuitry to extract clearer, low-distortion sound from your computer music sources. Apogee also employs a Quad Sum DAC™ design that combines the Sabre's eight internal DACs into a two-channel mode with four digital-to-analog converters per channel to give your music the highest possible dynamic range. 


High-res audio

Enjoy high-resolution audio

Along with all the sonic benefits the Groove provides for your compressed and CD-quality music files, it also has another trick up its sleeve — it decodes high-resolution audio streams of up to 24-bit/192kHz resolution, so you can enjoy better-than-CD sound. (There's a free USB driver download you'll need for Windows® PCs.) If you download high-res music files from HDtracks and other audiophile sources, this DAC ensures that you'll hear them in all their glory.

Features

USB-DAC & Headphone Amp: The Apogee Groove is a portable USB-DAC and headphone amp for listening to music on your Windows PC or Mac computer. The Apogee Groove takes the same high quality audio technology found in the world's most prestigious recording studios and delivers it to your laptop or desktop computer. You'll be amazed by the difference in sound quality; the precise stereo image, punchy bass, and stunningly clear highs.

Note: Your computer has a DAC and headphone jack built-in, however without a high-quality external DAC and headphone amp like the Groove, you will miss out on much of the subtlety, detail and dimension of music you listen to - regardless of what headphones or speakers you use.

Quad Sum ESS Sabre DAC Technology: The Apogee Groove features a Quad Sum DAC design which employs four ESS DACs per channel to achieve the highest dynamic range and lowest distortion (THD+N) of any device in its class. The Groove employs ESS Sabre32 32-bit Hyperstream DAC technology with Time Domain Jitter Eliminator to offer unequaled dynamic range, ultra-low distortion, and unmatched audio clarity free from input jitter. The Apogee Grove supports up to 24-bit/192kHz high resolution music files.

  • Frequency response: 10Hz - 20K +/- 0.2dB
  • Dynamic Range: 117dB a-weighted
  • THD+N (16 dBu): -107 dB with 600 load
  • THD+N (10.5 dBu): -100dB with 30 load

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 "HiFi" headphones, you'll discover a new level of fidelity, clarity, and detail.

Input & Output: The Apogee Groove USB-DAC and headphone amp is fitted with a microUSB 2.0 port and 1/8" headphone jack.

  • microUSB 2.0 Port: The Apogee Groove features an asynchronous microUSB 2.0 port for connection to your computer. Simply connect the Groove to your Windows or Mac computer's USB (type-A) port, using the 13" microUSB-to-USB cable.

Serious portable headphone power

Written by Dave Bar, Contributing Writer, on 9/27/2015 3:14:00 PM

Having had the good fortune to audition the full range of Crutchfield's USB headphone amp/DACs, I can happily testify that every one of them helped improve the sound of my music. But they're not all created equal. While all do a fine job of powering sensitive in-ear and portable headphones, some struggle to deliver enough juice to do justice to more serious audiophile and studio headphones. That's not a problem with the Apogee Groove! As expected, this potent little powerhouse easily pushed my lightweight Grado SR80s and Sennheiser HD 598s. But more impressively, it cleanly drove my Sennheiser HD 600s and even a pair of Audeze LCD-XC magnetic planar headphones to levels far beyond safe for long-term listening.

But sheer power isn't the only thing the Groove has going for it. Its detailed, insightful sound and vanishingly low noise floor seemed to make my music to leap out from an inky, jet-black background, especially high-res audio tracks. The Groove is also refreshingly neutral sounding; neither overly bright and analytical, nor sweet and euphonically colored. It feels rugged and well built, as befits Apogee's pro audio background. And I appreciated the Groove's non-slip rubber-covered base, as well as the fine degree of listening level adjustments available with its external volume control (crucial for highly sensitive in-ear monitors).

What else can I say except that portable DAC/headphone amps just seem to be getting better and better, and this is one of the best yet!

The Apogee Groove is a portable USB-DAC and headphone amp for listening to music on your Windows PC or Mac laptop/computer. It wouldn't be able to connect to an iPhone/iPod/iPad though. I hope that helps. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=159 [ Larry  May 04, 2016 ]  Staff
