Hey Paul, finally I’m also in the game and made the update (Snowmass 3.06-Windom)! Seems this thread is quite little used for whatever reason…maybe the task was too concrete 
But I admit, you didn’t make it too easy, at least for those not using streaming services.
First, those tracks are not what many already have in their collection I guess…second, the one or other album is not that easy to find… third, you didn’t mention the composer and which track you used from the Organ concerto… forth, you misspelled Allan Taylor… fifth, I recently deleted all my Allan Taylor files as, although they sound fantastic, they are really boring stuff for a jazznut (but that’s my problem).
So finally I got them all and made the move with them. Forgive me if I didn’t get all the differences due to the one time change instead of switching back and forth (but I had to make some notes).
But listening to the tracks I saw that you guys know what to choose…well suited to get essential differences!

Alexandra leaving:
Great track for testing! With Windom Cohen’s voice has more solidity and appears more in an own aura/air with better articulation. The female singer as well, she’s a little more in the foreground and the two voices are better separated with Windom in a bigger and much more natural appearing aura, very real sounding. Cymbals have little more color and natural sound. -
Tenessee waltz:
With the first guitar stroke it’s already obvious: Windom enables a more open, airy , ambient, “living” sound. The two voices speaking in the following are more solid and articulate and again less flat, more free in the room with Windom…air everywhere. The kind of tuning effect Taylor’s compagnion makes a few times with his string has straight away more ambiance, shape, openness and pop. The later appearing quiet background string sound is little more ambient and real sounding with Windom. -
Organ concerto:
Organ didn’t play a big role here, but the whole string sound in the room was quite transformed. First with Snowmass I heard a nice transparent soundstage with little better than average ambiance. A nice “better than average, not explicitely audiophile” recording like I also tend to use for testing (as it plays a role, how much “normal but good” recordings are improved). Windom then made Snowmass appear a bit flat with hifi like transparency compared to the vibrating life, realism and ambiance Windom added. It was too but less a clearly identifyable extension in soundstage or transparency, but more an enablement for the sound to breathe and the instruments to develop a bodily aura around.
Summed up, Windom in my setup has a noticably more lively, bodily, 3D, ambient sound which mainly cares for a more real and airy presentation, just like several are used from some characteristics of tubes/vinyl. Bass is tighter and runs out a little deeper without changing too much otherwise in my setup…just a bit richer, no sub phase readjustment necessary (I made the test). I just very slightly reduced the level of my bass chassis amp.
So the change was immediately noticable to the better in a direction usually everyone is keen on without any downsides. A smaller change than Snowmass was before, but in the very right direction…more natural, ambient, real. I certainly won’t go back to Snowmass and congratulate Ted to his latest achievements and Paul to caring for the right characteristics when voicing with those tracks!
