Thanks largely to Google’s Cast system, Wi-Fi speakers are rapidly replacing Bluetooth models. Wi-Fi units use your wireless network to transmit sound, and since they’re not subject to the data-transfer limitations of Bluetooth transmission, they have the capability to provide better performance. The Grace Digital CastDock X2 is rated to handle music files up to 24-bit/192kHz resolution.


I hadn’t heard much about Acoustic Research in a long time, though the name was very familiar. When I was in college, every other student who was on a budget but appreciated great sound had Acoustic Research AR-3 bookshelf speakers. These used an acoustic-suspension design that produced amazing amounts of bass from a small box. Then AR produced an affordable ($78!), high-quality turntable, the AR-1 -- a belt-driven design that greatly reduced acoustic feedback. Since then, AR speakers and turntables have only appreciated in value, as collectors continue to seek them out.
