Any comments about the JMLab Mezzo Utopia?

Is this a good speaker for rock and classical music? How much power does it need to be driven well? Can it play loud?
yes yes 50 watts and yes go and buy a pair.

Ya, what he said!
Not great for rock imho.

Better values out Dyn 1.3SE, Ann 25 etc.
Excellent for reproducing acoustic instruments. Not good for reproducing anything that is amplified/distorted/proccessed such as electric guitar or synthesizer.

I would recommend 100-200 wpc SS amps, but they can sound good with 50 wpc tube amps.
