The Denon AVR-589 is one of 10 new 2008/09 av receivers models announced by Denon on May 21st, 2008. The 589 replaces the previous-generation AVR-588. The AVR-589 is a 5.1 a/v home theatre receiver that features dual HDMI v1.3a inputs and HDMI output of up to 1080p, and a 32 bit floating point DSP processor. A notable upgrade to the previous-generation is the addition of Audyssey's Dynamic Volume processing along with the already present Dynamic EQ option. Dynamic Volume is found on all ten models; it's a feature that levels the volume to a more-or-less constant level to avoid sudden changes in volume. This feature works together with the Dynamic EQ that dynamically adjusts the EQ settings to optimize the dynamic range. The Denon AVR-589 has a suggested retail price of $299 and is expected to retail in July 2008 along with all other 2008/09 models.
