I just plugged in my airmotiv 5s speakers. I haven't yet gotten the DAC to work- may have to get another... Haven't set them in the right places... but still- very happy and looking forward to listening after a good DAC. Much louder than I imagined, and even though it's a little fuzzy without a DAC the tone is just wonderful. Like honey. Thank you for designing these Looking forward to really hearing them with better definition.
