Well, just got one, myself and I'm stunned. The detail, cleanliness, and DEPTH ... my god! It's pretty freaking amazing. Has anyone else had issues with the connection being lost to the DAC, though? Sometimes if I touch the usb cable, the computer switches outputs like the Magni's been disconnected. It's not consistent, though. Sometimes I barely touch it and it happens. But sometimes I can shift the plugs around within the sockets at either end and nothing happens. But if I don't touch it at all, it plays fine for hours. I don't have this issue with any other usb devices — certainly not any audio devices.
I don't have the Magni Unity but my Nitsch Pietus Maximus would cut out the right channel if I touched the input switch (between RCA or USB DAC) just a little. I sent it back to Ceetee for repair. He swapped the circuit board and it's all good now. You shouldn't have any issues at all when plugging in a cable or flipping any switch.
