When you think of Samsung, you probably think of excellent Android smartphones like its Galaxy S devices or its many high-quality TVs. That's perfectly justifiable, too, as Samsung is one of the best brands in both market segments, with customer satisfaction ratings to prove it. One industry you might not necessarily associate Samsung with is audio — more specifically, audiophile-approved, Hi-Fi audio. Samsung owns a good chunk of prominent audio brands, many of which have serious heritage and cachet. Sound United owned brands like Bowers & Wilkins, Denon, Marantz, and Polk Audio, which became subsidiaries of Samsung once the deal was done.
