The electronic components that accompany Wisdom Audio's speakers aren't new, but they sure look cool. This rack includes an SC-1 system controller, which provides electronic crossovers and Audyssey MultEQ room correction, and several SA power amps with one, two, or three channels of amplification at 500Wpc into 4Ω. Combined with Wisdom's in-wall main speakers and standalone subs in the company's demo room, the system sounded fantastic—in fact, it was one of the best audio demos I heard at the show.
