SP3 Surround Preamp / Processor


The Bryston SP3 sets a new high water mark for audio performance in a category dominated by inexpensive receivers that are obsolete after a few short years and never really performed that well to begin with. Theater enthusiasts who put sound quality first will love the SP3's pedigree. The same proprietary discrete operational amplifiers we've designed for our premium 2 channel products are used here. Digital to analog conversion is rendered with bit perfect accuracy, and a host of configuration options and control possibilities are compatible. There may be surround processors that have more or newer features, but you will be very hard pressed to find one that is more enjoyable to use and listen to. Upgrade your theater with the Bryston SP3.
