“Audioengine makes some truly remarkable products and they are a company I’ve been impressed with for quite some time. It’s an impressive little box and it brings new meaning to good things come in small packages. Before playing any sound through your output speakers, I would recommend turning the volume down on the DAC, your input device, and speakers (if applicable). When I played music through the studio monitors, it ended up causing Robyn to have a headache the rest of the night because of the power behind the sound. The Audioengine D1 DAC Headphone AMP is a really great investment if you are faced with a digital-to-analog audio roadblock like I was.” —— macsources.com
