The Orion's DSP both Noise Blanker and Noise Reduction are awesome. For the
first time, I can hear Europeans on 75 meters down here in Florida, the
lightning capital of the world.

I can't speak for the Orion's dsp, but my audio dsp does better noise
reduction and better CW S/N when it has more input bandwidth, rather
than narrow. This I suspect comes from narrow band noise being more
correlated than wider band noise which makes the algorithm for noise
rejection work better with the wider band noise.
