Spinal Tap’s legendary amps were “one louder” by going from 10 to 11. Onkyo’s new home theater receiver model went one better, by going from being called TX-SR605 to now TX-SR606—but more than one feature has been improved.

The TX-SR606 includes upgrades such as adding 1080i video upscaling, two more HDMI inputs to let the receiver now handle four total HDMI sources, Audyssey’s new Dynamic EQ loudness compensation technology, and the company’s proprietary Music Optimizer circuit.

Onkyo’s upscaling technology takes standard-def signals and brings them to 1080i, with Faroudja DCDi Edge technology helping eliminate video artifacts, the company says.

Your MP3 and AAC encoded compressed audio will sound better too, thanks to the Music Optimizer software. For full-throttle uncompressed sound reproduction, the TX-SR606 has 32-bit DSP processing and 192 kHz/24-bit digital-to-analog converters on all channels.

For aesthetics, the receiver comes in black or silver finish. It’s due out this month, with an SRP of $579.
