I'm the author of the review referenced above by James. If anyone has any questions or thoughts, I'd be happy to hear or respond to them.
James, I wanted to add the following thought to what I wrote earlier. Since sending you my comments, I've had much more time to continue the dive into my music library, including older recordings that I hadn't listened seriously to in years. It's been a lot of fun.
Many recordings are again sounding as I either knew they could, or assumed they should. They are revealing nuances and dynamic colors that I'd heard previously on mightier systems than I personally owned, but weren't as audible in the passive speaker version. In some recordings that are newer, I feel like I'm getting more value for money paid for the music.
The active system upgrade has caused one unexpected knock-on effect though. It's stimulated some pretty significant "cost overruns" in new music purchases . . . no apparent end in sight . . .
