That sounds like the DL1608 has a feature that the X32 doesn't and would be nicer if it did!!!!!!!!! I thought the X32 was a God-like item that had every feature that anyone would ever want and the DL1608 was missing nearly all of them.
Back to reality. Being that most analog boards don't have any serious EQ on Aux outputs, the DL is a practical move up that ladder. I'm not sure if they needed both PEQ and 31 band EQ, but it doesn't hurt. (And please leave the 31 band alone. I use that one a lot.) Anyway, thanks for pointing out that the X32 has some shortcomings that might take it out of the running for some people. (For me, besides too many channels, it's too large and probably too heavy.)
