Versatility at its best. The AVR645 not only switches two HDMI 1.1 sources it is able to decode Dolby Digital, DTS and PCM audio streams from the HDMI inputs. Add USB audio and iPod connectivity to Harman's EzSet/EQ system and high-current amplifier, and the 645 performs with ease. Equally impressive on the video side is format conversion so that all analogue video inputs may be viewed via component outputs, and Sync Delay, which reconnects the timing of sound and images. There is no better combination of sound and image anywhere.
