Also have not heard the ANV-50, but have owned an older A21SE rated at 33wpc class A. It is scary and I've used it with many speakers to include Reference 3A towers, Merlin Black Magic, Penaudio Cenya and a myriad of others not particularly efficient.
The control 33 watts of class A has over the overall presentation is impressive. Music springs from the speakers as attack is much more immediate than most A/B designs. It will not rock the bass nor plumb the depths. Look elsewhere. But within its design space, it is glorious.
Soundstage is decent, attack is stellar and it is simply quite musical. The bass present is distinct. Speaker cable selection is a bit tricky. Decware hybrid copper/silver seemed to do the trick as did Duelund 12 gauge. Silver wire was thin and edgy.
Hope this helps.
