SA-8125 Signature 8-Channel Amplifier

Our team has decades of experience in amplifier design and has put all of it into this outstanding line of amplifiers. While they are built to audiophile standards they provide features that are needed for flexible multi-room installations. Multiple subwoofer outputs, easy assignment of sources to channels and optical inputs are standard on each amplifier. Every part of the amplifier has been carefully considered and built for the best possible performance. While other manufactures would use digital power supplies we use toroidal copper power supplies for reliability and performance. We have chosen a smaller manufacturing partner that only does amplifiers and has a decades long history of manufacturing some of the best amplifiers ever made. We back all this confidence in our performance and reliability with a unique 5-year warranty.
