Thanks for sharing @digsmithd , thanks for taking the time to update the thread with your impressions. As you say, likely you will hear more improvement down the road with more time to stabilize and settle in.
For what is worth, I will copy paste below what I wrote last year in October half way through my Zavfino journey then:
What I have found with Zavfino is that they react very well to “full loom” concept. Meaning all cables from the same brand, and preferably same tier of same brand.
I am gradually getting there. The more I add, the better the overall system sounds as a whole. The improvements are cumulative, and I believe mostly due to the full loom concept.
