Man, I can relate. I still haven't had time to figure out my DCX, in order to maximize its capabilities. I only have the HPF for my subwoofers and the crossover frequency with the mains set, so far. I've downloaded REW, but that's as far as I've gotten.
Perhaps after I get the HT finished downstairs, I'll find some time to mess around with it. Probably not....
By the way,
thank-you - I now have your cold. I had no idea the internet could transmit the cold virus as well....
