So I downloaded and started using 28 after not using my system for quite some time. I set it up to play from memory and started listening. When John Mayer was playing, my wife (who streams Mayer all the time) commented that it sounded a little "fast."
As I listened to stuff I was more familiar with, I thought "hmmm...it DOES sound a LITTLE fast," but then thought maybe it's my brain/perception getting skewed from her comment. Mind you, it's a VERY small difference.
In researching, I find a previous post from a few years back about others (with a previous version) finding that they had the same problem when memory playback was activated, and turning it off solved the problem.
So I turn off MP, and lo and behold, it's back to normal. Without telling my wife, I play Mayer with MP off, and she comments that it sounded "normal" now.
I haven't tried timing it yet (too busy with work), but am I (and my wife) just crazy?
