I downloaded the Dream package and put it on my computer.  It did take a
short while to get anything useful out of it, but it does work.

So far the biggest benefit is the audio spectrum analyzer display.  I was
looking at the difference between analog AM and IBOC.  Analog is anywhere
from 4-5KHz while IBOC brick-walls at 15KHz. FWIW, FM is 15KHz analog and
20KHz IBOC.  With my ears, I can hear no difference.

As to pulling things out of the mud?  So far, nothing to report.  I have a
TimeWave DSP-599zx which does a very good job.  I haven't been able to get
the Dream to come close, but I'm way down the learning curve.

I have very little selection of DRM signals, and no 12KHz IF output from the
Drake, so that ain't gonna fly.

I'd be curious to hear your results, especially with the huge number of
command line options.  There's a whole alphabet of trailing letters to set
options according to the help file.
