The NuForce Reference Series stereo amplifiers are designed for both high-performance stereo and home-theater use. They can be used for bi-amping, tri-amping and home-theater mixing-and-matching when used with NuForce AVP (Audio-Video Processor) products. The Reference Series stereo amplifiers are standardized on a platform consisting of amplifier, power-supply and capacitor modules, any of which can be upgraded when new technology becomes available. Advancements in technology will never render NuForce stereo amps obsolete.
