Yes that would be the first question. Is the iFi device even on?
I don't see the need forthe iFi device; I'm glad that @lowrider57 enjoys his product, but any DAC worth it's digits these days should be able to store the feed in a buffer and reclock it to remove jitter from the source. If the Node is that bad in relation to jitter, using a device like this sounds like having a broken axle on a car and putting duct tape on it while you drive twenty miles to a service station
