If you are hooking the Proceed to another digital input at the same time this could the your problem for example a cd recorder. Have you tried the Proceed with another DAC. I have a Kora and mate it tothe Electrocompaniet with excellent results - no noise of any kind. It is not over-rated at all. Only a person who doesn't have one or hasn't heard one could say that.
Proceed Transport & Kora DAC compatability problem
I just bought the new Kora Hermes DAC and have run into a problem. I have a Proceed PMDT transport and the Kora is not reading the output from the transport. It will not play using the PMDT. I hooked it up to an inexpensive Phillips CDR and using the digital out it plays fine. Is anyone aware of this problem and if so is there a solution short of getting a different transport or returning the KORA. You help is appreciated.
