We are looking at this differently. I see the eq as a one time only purchase. If I felt the need for full eq I could purchase an external unit to run with our Model 975. Come upgrade time unplug the 975, plug in the new processor with no new wires. We could upgrade to any channel configuration supported by the processor with the only new wires being between the external eq and the amplifier channels for the new speakers.

If you think about how much full function pre/pros can run, not buying eq every time you upgrade the expense would break even quickly.
