Noisy optical input

SAM does do level dependant DSP correction based on the power handling spec of the drivers. Setting a fixed 0dB level on the Devialet and adjusting the actual level elsewhere will defeat this capability (giving reduced bass since SAM will be protecting the drivers from a level much higher than the actual) and is almost certainly going to reduce potential sound quality anyway.

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.
