Some things to consider:
To my ears the Met 7's are the most interesting choice. They are classics that have some musical qualities that none of the others do; imo. They can sound really really good, and are very sophisticated little speakers. But you will need stands. The subwoofer (if set up well) will relieve the NAD of needing to power lower bass and will add weight to the sound. The Met's are efficient, but the NAD (also a classic) is not exactly a powerhouse. For my tastes, if you don't plan on playing a lot of very loud music, these sound more like music than the others.
The Paradigm's are the most efficient, and would be my second choice if
you want a floor stander and is probably the safer choice all around.
The Vandersteens are also good, but so is a Honda Civic :-)
