This is one of my favorite movements (I've written 35 symphonic movements so far):
Symphony #6, 1st movement

Enjoy??? It is truly magnificent (and profound)!! I gotta chase a couple of those scales down.

Lots of work went into this!  I think the results speak for themselves, it's great.

+1 to the above...    it certainly is up to your standards! 
 
Really good dynamics throughout both in arrangement and key-switching, some very cool string lines, and loved the mouth harp (?) accents. 
 

I like, nicely captured, good arrangement and composition, some nice bits that made me smile.  

So my question is "Where does that "E major triad-C minor triad scale" come from? It's beautiful.

got it!! double harmonic minor, right?  (upper tetrachord)

So my question is "Where does that "E major triad-C minor triad scale" come from? It's beautiful.

This chord is not derived from a particular scale.  It is what is known as a polychord, the juxtaposition of two triadic chords in a chromatic double mediant relationship (c-e being the "mediant", "chromatic" meaning not part of the major-minor system of chords/scales, and "double" meaning that one chord is major and the other minor. 
 
If you take the 6 notes of both chords you'll have c-eb-e-g-g#-b, so there's your scale!

See my posting describing those chords (not double-harmonic minor)

I found myself intrigued by what wold come next. Stellar.
