AO is great, no bones about that but there is always a reluctance by any seller to replace equipment when you suspect the problem may not be with your equipment!
In this case I also have a nagging feeling that bad cables, PC's or grounding issue's may be the problem, but at some point one has to except that the consumer has tried everything in his power to resolve the issue and just exchange the unit to keep good customer relations. It's very frustrating when your trying to solve a problem and a little voice keeps telling you, "Your wasting your time the problem is in the Controller it's a dud"
I know how that feels, it sucks the enthusiasm right out of you.
