I used this transformer and it works (with Benchmark DAC1). Be careful with the 6MHz Canare transformer bandwidth since protocol requires always 64 bits per sample (32bit per each channel)
44.1kHz x 64bit=2.82MHz OK
96kHz x 64bit=6.1MHz OK
192kHz x 64bit=12.3MHz Not working
Protocol is pretty much the same but characteristic impedance and levels are different. Since you need to get from S/Pdif to AES/EBU you need to change characteristic impedance from 75ohm to 110ohm and increase voltage from 0.5V to 5V (active circuit or transformer required)
Bandwidth limit of 6MHz will also slow down transitions to about 27ns. It won't affect typical player that has about 25ns transition but will affect more expensive transports' faster transitions - for better or for worse. I wouldn't worry about it now since it is system dependent and effect are unpredictable. Transformer is cheap and also sold on Ebay where I bought mine. Be sure it is BNC to XLR and not the other way around (XLR on transformer has to be male). Use number Drubin provided to avoid mistake.
