I regret selling my Theta Casanova when I did. I should have kept it for much longer, and if HDMI was a real option I would have. In other words, don’t "trade up" unless you know it’s actually a trade up for you. It’s good to get suggestions, but make sure you listen for yourself first.
I’d consider room acoustics if you haven’t already, especially in a new space. They can make speakers sound much larger by taming excess mid-treble energy and smoothing out the bass.
The one thing I'd strongly urge you to add if you havent' already though is a streamer. Access to unlimited libraries of Jazz, Classical plus online radio like Jazz.FM is priceless.
