I was nearly put off buying this by Ms Spotheim's review as I already have the excellent Von Stade/Abbado/Ponnelle version but, as a fan of Florez, decided to give it a chance at Amazon's currently very reasonable price and am glad I did.
I played the disc on a Sony blu-ray player on a Sony Bravia TV through a Yamaha amplifer/speakers set up and didn't find the sound a problem - a bit brash at times but the voices were true to what I have heard of the principals in the theatre. As anticipated, Florez has the role right in his voice and is a total pleasure. Ms diDonato is more than adequate and, even if she does not have one of those instantly recognisable voices, is infinitely preferable to Cecilia Bartolli who, for me, attacks the role in a way that takes away the vulnerability of Cenerentola (and I found my self agreeing with the sisters when they tell her to stop droning on about the 'Re' in her repeating 'leit motif' song) and she overacts to an astonishing degree. Also, I find the way she (Bartolli)adopts that pecking motion when she sings coloratura very unpleaseant to watch - a personal reaction I know but ... Dandini and the supporting cast are fine.
The one thing that lost the disc a star was the production, supernumaries scurrying about on all fours in rat masks outstay their welcome very quickly, Dandini's push-me-pull-you horse is just plain odd and the male chorus guy their entrances as seems to be the way with most productions of Cenerentola I have seen. Ponnelle's production now shows it's age in it's filmic style but would still be my top recommendation for this work - von Stade is simply adorable.
