As far as sound quality, a single Vidar should sound better than a bridge pair if the single is doing it comfortably wattage wise, although you don’t have the wattage with a single, than you do with bridged pair.
Negatives with bridging amps:
1 More distortion
2 Less damping factor (higher output impedance) "bass control"
3 Less current ability
4 Not able to drive as low impedance as non bridged.
Positives with bridging:
1:More wattage
As for speakers if you look at the above, single or bridged Vidars
For inefficient (<85db) speakers, that have an easy'ish impedance load (>4-8ohm) go with the bridged Vidars
For efficient speakers (>85db) that are a not so easy load (2-4ohms), go with a single Vidar.
