Nevertheless, with the increasing role of software in audio processing there is tremendous benefit to having at least some things that can be upgraded via a flash or a module swap out.

And its not just a customer benefit. For example, lets suppose that the DAC chips were on a swapable module. I can't believe that Outlaw couldn't make a nice profit on an "optional DAC module" that offered substantially better performance then their standard components. Locating the main processor chip and its memory on another module could allow them to sell upgrades and additional functionality that might require more processing power then their first choice processor had (e.g. entering the the exact distance for each speaker for surround sound).
