Problem using Monarcy DIP Classic with cablebox

Hi,

Every time I switch music stations on my cable box with the Monarchy DIP inserted I get an etremely loud hum/buzz/hiss coming out of the speakers. If I have the Audio Alchemy DTI inserted in its place I get no such buzz. I think the Monarchy sounds better and would like to use it. Is there a way to eliniate this noise?

Thanks,

Pete
