Dirac is a new addition to both AVR's the 550 & 850. Dirac is a powerful tool in correcting a speakers frequency response in your room by reducing peaks and lifting troughs to achieve a near perfect EQ curve. This allows every speaker particularly subwoofers to breathe without that "congested" or "boomy" room response which helps reveal even more of those finer details that were once masked.
The AVR850 isn't just a great AV Receiver that plays Music & Movies well, it excels in both, the AVR850 is a force to be reckoned with.
