Onkyo's latest feat, the TX-RZ800 is a prime example of the company's commitment to outstanding quality and performance, having been designed specifically to cater towards the audiophile aspect of the market, the unit boasts an unrivalled sound quality with Onkyo's world-famous build integrity and innovative design principles. 

High-current transformers, built to Onkyo's custom specification, work alongside separate amplification and processing blocks, as well as custom-designed capacitors, Asahi Kasei 384 kHz/32-bit DAC chipsets, and discrete, low-impedance amplification circuitry. Alongside these audiophile grade bits and bobs, a 32-bit digital signal processor aids in retrieving every ounce of dynamic detail from the latest surround-sound formats, including DTS:X and Dolbt Atmos. 

Onkyo have also used Vector Linear Shaping Circuitry (VLSC) tech with the RZ800, which is designed to clean the signal of pulse noise in order to further enhance the quality of the sound being processed within the unit. The RZ800 is ready to handle all of your sources, and includes support for HDCDP2 4K 60Hz video pass-through. 

The RZ-800 is not only packed with high-quality materials and components, but also has a tonne of up-to-date bonus features as well. These include direct streaming functions from Deezer, Spotify, or AirPlay, Bluetooth and TuneIn radio.
