I downloaded the sneak preview version and got a couple of hours with it tonight.
The difficult part of evaluating a firmware update is that it’s difficult to do A/B testing.
That said, two things stood out to me on my first listen to Windom. The first thing I noticed was that the music seemed more “real” and clear. Difficult to describe this quality exactly, because it was more than just detail, it the music actually seemed a bit more genuine and authentic. The second thing that I noticed was a slight increase in dynamics. The music seems to have a bit more punch than it did before.
I’ll be interested to hear your impressions on this too!
