Are these exceptionally well recorded, or what?

I don’t know what just happened. My system suddenly started to sound much, much better. Particularly on the last three Qobuz hi-Rez downloads. What happened? The last change in my system was two months ago—added the new Bel Canto PRE5 preamp. It sounded great right from the start, and I probably have 120-150 hours on it. Can it have “snapped in” all of a sudden?  Is my power suddenly cleaner? Or did I stumble on three exceptionally well-recorded albums.  I’ll listen to my old standard references, but in the meantime, I’d like you opinion of these three:

Marie Stockman Becker: JS Bach Sonatas for Viola (on this album I can distinguish between filters on my Cambridge 851N, for the first time).

Veronica Swift: This Better Earth (opening song—she’s right there in the room)

Rattle and the LSO: Rachmaninoff 2nd (best sound staging I’ve heard on this system).

whattya think?
