The cable seems somehow too simple. I was under the impression that the data format was different in an spdif or an AES stream, maybe I am wrong, I genuinely have no idea.
if the cable does the job, that would be great. I could maintain all the functionality of the Node, which I really like, while upgrading the dac (allegedly the weakest part of the node) and getting a very different flavour of speaker.
At less than £30 the cable might be worth a try... There are other converter but since it's S/PDIF I wouldn't a cheap one.A quick Google suggests there is a tenfold difference in expected signal levels between the two (0.5 V vs 5 V). Whether this causes an issue will probably be hardware-specific?
