As per title, is this possible?

Some context: I've recently acquired a Auralic Altair which, amongst others, has a AES/EBU input:



I no longer own a digital source with a AES/EBU output and in order to maximise my options, I'd like to use any SPDIF digital source and plug it into the AES/EBU input. I've not been able to find a definitive answer and have tried one of these, but it doesn't appear to work:

EDIT: I am concerned the Neutrik device I purchased from eBay might be faulty, but can't be 100% certain.

Am I on a hiding to nothing?
