The PX-650 represents a successful blend of digital audio technology with Accuphase's rich expertise in the field of analog power amplifiers. The result is a six-channel digital power amplifier ideally suited for high-end home theater systems. Because six identical high-efficiency power units operating in digital mode are used, all channels provide the same excellent sound quality.
The PX-650 can drive any kind of speaker with ease and authority, creating a spacious surround sound stage with pinpoint imaging and impressive dynamics. Thanks to its high efficiency, the digital circuitry keeps thermal energy generation low, making it possible to reconcile high output power levels with compact unit dimensions. This is especially welcome in multi-channel systems for home theater applications.
