Are you suggesting that anything that affects volume (like digital room correction through a computer) placed before the Spark would defeat the SAM?

I think f1eng may have misunderstood a little here. SAM is sensing the actual signal driving the speaker so should do the right thing irrespective of the digital level of the source material. The DSP correction is not locked to fixed levels.

You are quite right, I was wrong about sam.
I still don't see the point in not using the Spark volume control. It is unlikely for an alternative to be any better.
