This is a music hall dac25.2 in excellent condition. It has a black main case, with a silver faceplate. It is in very good condition (a few minor scratches in the black case), but works perfectly.
I have been using it in my system to provide conversion of the digital output from my Zune (the Zune dock features an optical output which the 25.2 accepts), and from my PC via a USB cable (I have been using it with Windows 7; no special drivers were required). The unit also has coax S/PDIF and XLR (AES/EBU) inputs, and RCA and XLR (balanced) analog outputs.
The sound quality is excellent; it also has options for 96k and 192k upsampling if you prefer. There is also an on-board headphone amp with a 1/4'' jack and volume control on the front of the unit.
I am selling because I have replaced it with a Logitech Transporter and no longer require it.
I will pay shipping (I have discounted rates via UPS) within the US. Buyer to pay shipping if International. Buyer to add 3% if paying via PayPal.
