Audioengine doesn’t know when to leave well-enough alone. Case-in-point: Their A2 speakers were just about the perfect size and rating for desktop use, and consumers obviously agreed because they have sold quite well. Even so, Audioengine figured they could do better, so they’ve introduced the new A2+ powered desktop speakers. These mini-powerhouses have been substantially upgraded from the original A2s, featuring an on-board digital-to-analog converter (DAC), upgraded speaker connectors, standard threaded inserts for wall mounts, an upgraded power supply, and accessory cables. They also include built-in 30-watt per channel amplifiers, USB audio input, hand-finished wood cabinets, and custom Kevlar woofers with silk tweeters. Since the A2+ includes a DAC, they can be connected using USB, insuring a total digital output resulting in a cleaner signal. If the A5+ speakers and D1 external DAC are any indication, the A2+ speakers should be well regarded. They are available now for $249/pair.
