When it comes to luxury sound systems, McIntosh is in a class of its own. The company's latest wi-fi stereo supports AirPlay streaming and features a dynamic soundstage that bumps serious bass from its loudspeaker set, which houses dual 4-inch woofers, 2-inch midranges, and .75-inch tweeters. Ethernet and RCA inputs are also present.
