I have a like new NuForce Icon UDAC-2 for sale. I still have the original packaging. I bought it to use with my Cowon but it is not the right application. This also can be used as a USB to SPDIF converter. It sounds awesome and is powerful enough to drive original 600 ohm AKG K240 M cans. It is very surprising for it's itty bitty size. I want $75 firm plus shipping.
