Onkyo has upgraded its most popular HDMI-1.3a-capable home theater receiver by adding 1080i video upscaling, two additional HDMI inputs to handle a total of four HDMI sources, Audyssey's new Dynamic EQ loudness compensation technology, and Onkyo's new Music Optimizer circuit. The new Onkyo TX-SR606 replaces the company's best selling TX-SR605.

This receiver also has a powerful 90 watt-per-channel amplifier section, Remote Interactive control over HDMI (RIHD), is Sirius Satellite Radio ready, and offers a full range of advance surround sound codecs, including Dolby TrueHD and DTS-HD Master Audio to provide lossless bit-by-bit audio identical to the master recordings.

It will be available in black or silver finish in April, for a price below $580.
