Quad-DAC Design, Constant Current Drive

With the Groove, Apogee applies its expertise in professional audio devices to making a compact, powerful DAC/amp for Macs and PCs. Featuring a quad-DAC design that uses four DACs per channel, this unit provides the highest dynamic range with the lowest distortion. It can drive demanding headphones with ease and doesn’t require additional power beyond a USB connection. Outputting 225 mW at 32 ohms and 40 mW at 600 ohms, it’s a particularly good fit for the Massdrop x Sennheiser HD 6XX, as well as the HD 650 headphones—and it makes a great pairing for the iPad Pro. The Groove also comes with a unique feature: the constant current drive. By making adjustments to the current, rather than the voltage, this allows the amp to deliver a smooth frequency response and lower distortion with a variety of headphones. 

The Reviews Are In

Head-Fi user acain says, I would highly recommend the Groove to anyone looking for a portable amp/DAC for their laptop. Its form and build are top-notch; its higher price might turn away the average consumer. If you're an audiophile or a serious music lover or a pro in the industry, the price will be more of a bargain for its performance. It’s not every day I get to demo something that gives me that WOW factor. The Groove has definitely shocked me. Just for being a portable unit and its size, I didn’t expect it to drive headphones the way it does. I was even more impressed [by] the way it converts all those zeros and ones into a highly detailed listening experience.”
