For a Living Room Sound System
Q: How can I get a great-sounding system that doesn't take over my living room?
A: Start with the tiny but powerful PS Audio Sprout ($799; psaudio.com). The 50-watt-per-channel amp works with analog sources but is built for streaming music: An onboard DAC (digital-to-analog converter) smooths out the sound of Bluetooth audio streamed from your phone or computer. Pair that with the bookshelf-size Bowers & Wilkins CM5 S2 ($1,600 a pair; bowers-wilkins.com), whose tough composite drivers and 1-inch tweeters — separated from the cabinet via a ring of cushioning gel — re-create the fuller, more natural sound of larger speakers.
