M2tech Evo USB converter

M2Tech hiFace Evo USB Computer Audio Interface flawlessly transfers data from USB equipped computers to virtually any DAC. Asynchronous operation up to 24/192kHz.. Much better than the hiFace. Outputs include: coax on RCA, coax on true 75 Ohms BNC, AES/EBU on male XLR, optical on Toslink™ (Toslink™ is guaranteed to operate up to 96kHz, though we got operation up to 176.4kHz on certain setups), optical on ST (for high-speed operation up to 192kHz and up to 1.6km or 1 mile), straight I2S for direct connection to DIY DACs on RJ-45 (NOT plug-in compatible with NorthStar products!) Includes an external wall adapter for power. Power source options are available (but not included) including battery power supplies. Drivers and owners manual can be downloaded from M2tech website for Windows XP, Vista, 7 and Mac 10.6 (not sure about Lion).
This is in mint conditon and I'm asking half of the original selling price. Only $250 plus shipping and Paypal fee at 3.5%.
