While new technologies come and go, the fundamentals of competent receiver design remain constant. It is best to think of it in simple terms: a power supply, an input stage, a driver stage, and an output stage that all combine to amplify signals without any loss in quality. The current that actually drives the loudspeakers comes from a power source via the receiver’s power supply. You can never underestimate the importance of the power supply, and all other audio processing functions cannot rule over good solid amplification. This is the direction Onkyo has taken with the Onkyo TX-8222. Built for those people who value the benefits of time-proven amplification design, the Onkyo TX-8222 takes core Onkyo technology—and an array of features you’ll actually use—to bring you a no-nonsense stereo receiver that will deliver audio and radio signals with agreeable quality.

Forget about over-hyped processing technologies. If your receiver lacks the fundamental amplifier design from the power supply through to the output stage, everything else is superfluous. The Onkyo TX8555 stereo receiver is built with this in mind. Incorporating Onkyo’s proprietary Wide Range Amplifier Design (WRAT) with an isolated power transformer and discrete output stage, the TX-8555 is focused on maintaining the purity of music, radio and video sources.
