From hi-end audio maker, PS Audio, comes the minimalistic stereo amp for those who don’t need a whole lot of complicated gear. Sprout: The Hifi Stereo Amp that transforms the way you listen ($499) is about the size of a large novel and allows you to listen to music from any bluetooth enabled device, your turntable, computer, CD/DVD player, or even your old school reel-to-reel tape deck. On top of its versatility, it just plain sounds great. Sprout is able to play high resolution 192kHz/24-bit audio while supplying plenty of power. If you get the unit from Kickstarter your save about $300 over retail.
