There are good technical reasons to Windom better than Snowmass - it’s not just a “reflavoring.” (And you’ll have the same people deciding which of 20 compiles to use as you did in Snowmass.)
For my part, each change was only motivated by trying to get more crap out of the way of the sound. E.g. using fewer of the resources in the FPGA that generate the most noise (something we learned about in Snowmass.) And I did a little more of the “Huron -> Redcloud” type changes as well.
I had high confidence that based on the technical changes it would sound better, but I was mildly surprised at the report of more fullness. To me, here, it’s simply nicer to listen to and I knew it was better technically. In hindsight I think I can understand where the “fullness” comes from, but I’m not positive - I have two good contenders, perhaps they both helped.
If anything, Windom will have less distortion the Snowmass, especially with the volumes near the top.
