Design: Measuring 17.4 inches by 12.94 inches the Onkyo TX-SR607 has a rather large footprint. Following the big-and-bulky design school the A/V receiver comes in either silver or black. Featuring a front panel with a HDMI port built-in amongst all the controls, the A/V receiver is simple and easy to use. It comes with a similarly simple remote control utilizing a mostly menu-driven text-based interface.
Specifications:The Onkyo TX-SR607 offers built-in decoders for DTS Neo:6 , DTS Express, DTS-ES Matrix 6.1, Dolby TrueHD, Dolby Digital Plus, DTS-HD Master Audio, DTS-ES Discrete 6.1, Dolby Pro Logic IIz and Dolby Digital Surround EX. Connection-wise the A/V receiver offers six HDMI inputs, two optical audio inputs, two component video inputs, two coaxial audio inputs, two stereo analog audio inputs and five composite AV inputs. It may support as much as 8 HD devices at any given time. The receiver also offers Onkyo's universal port for other Onkyo devices as well as two sub-woofer outputs for dual sub-woofer setups.
Features & Performance: Establishing the Onkyo TX-SR607 is easy using the Audyssey 2EQ speaker calibration system. While the sound quality is excellent out of the box some audio purists could find the sub-woofer volume too loud. Other features of note include basic multi-room functionality for additional flexibility.
While the Dolby Pro Logic IIz support doesn't seem to add much in atmosphere, other more traditional standards offer great sound on mid-range levels, with superior audio layering and great audio separation. The receiver could be powerful when it's needed and deliver accurately natural trebles when needed too. Analog to 1080i is simply above average with better recent results for lower resolutions.
