Thanks to participation from the Audiophile Community, this version of the ODAC features a few improvements to the original you won’t find elsewhere. For one, it’s designed with the same dimensions as the O2 Headphone Amplifier, offering a streamlined aesthetic when used in tandem with the amp. And in addition to the 3.5-millimeter output, we’ve added RCA outputs for near-universal compatibility. Use it with your favorite headphones, or hook it up to your stereo system or pre-amp.
