SVS Prime Wireless Pro speaker system ($899.99)

Active speakers with built-in amplifiers and streaming capabilities have been the hottest trend in hi-fi for the last few years, because you just plug them and use your phone or the Internet as a source. The Prime Wireless Pro not only sounds really good, it offers some nice extra conveniences, such as a subwoofer output; six programmable content presets (so you can immediately access, say, a Sonny Rollins playlist or your favorite jazz station); and an HDMI eARC input that lets the speakers work like they’re part of your TV.
