I have no problem in shipping the DSP up to them. I can run the speakers with just the fronts (sans dsp).

It is an interesting poser. As there are simply just too many variables to really point the finger at the cause of the problem. All we can really do is eliminate the likely causes and see what falls out in the process. I know I am in good hands and Andrew is onboard to trying to figure out what is causing this. I'm in good hands as they say.
