Great sound would be the overwhelming pick at any audio savvy site. It is the second most important deciding factor that would be up for grabs. I'd think sleek looks is what matters to the typical spouse.
Given the lack of popularity of active speakers, I wonder how sincere folks out there are about great sound. I personally would never consider anything less than Mackie, Genelec, Dynaudio or PMC monitors for the primary audio system. At some subliminal level, even the "lifestyle" speaker haters are caving in to matters of style and presentation.
