Doesn't have a USB input, so if you wanted to use it digitally off a PC, you have to use something to convert the USB into SPDIF like the SMSL PO 100, and then convert the SPDIF into AES/EBU like the Canare transformers. Price of the unit is $350+price of the mod kit is another $140 USD+there is sweat equity of doing the DIY mod. Comes to over $500, and, in the end, won't be as performant as most current DACS.
When you consider that a brand new MiniDsp Flex 8 is $599, and does everything this does with two more output channels. and has the $199 option of adding Dirac Live to it, and will almost certainly have Sinads from all eight of its DAC channels exceeding 110 db, I don't see why this modded Behringer would be an option unless someone wants to tinker.
