      6. Amplifier

      Onkyo TX-NR626 Pioneer VSX-831

      7 channel Amplifier: Onkyo TX-NR626 features 7 channel power amplifier. It is rated at 95 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      5 channel Discrete Direct Energy Amplifier: Pioneer VSX-831 features 5 channel power amplifier with Discrete Direct Energy design. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).
      • WRAT (Wide Range Amp Technology): Onkyo TX-NR626 features Onkyo’s Wide Range Amp Technology (WRAT) circuit layout that prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image. If phase shift occurs and signal timing is not accurate, then neither is the resulting audio image.

      7. Speaker Configurations

      Onkyo TX-NR626's and Pioneer VSX-831's amplifiers can be assigned for different speaker configurations.

      • Configurations: Available configurations are:
      • Onkyo TX-NR626: 5.2, 7.2 with internal amplifier.
      • Pioneer VSX-831: 5.2 with internal amplifier.
      • 2-ch Bi-Amp: Both models are able to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

      8. HDMI

      Onkyo TX-NR626 comes with 6 HDMI inputs. It has 2 outputs which work parallelly and output the same signal.

      Pioneer VSX-831 comes with 6 HDMI inputs. It has 1 output.

      • 4K/30Hz Passthrough on Onkyo TX-NR626: All inputs pass up to 4K/30p video signal.
        4K/60Hz Passthrough on Pioneer VSX-831: All inputs pass up to 4K/60p (4:4:4 24-bit)
        4K/60p (4:2:0 36-bit)
        4K/24p (4:4:4 36-bit) video signal.
      • 4K Upscaling: Both receivers can upscale up to 4K/30p (Marvell Qdeo) from HDMI and analog sources.
      • Analog To HDMI Upconversion: Both receivers support analog to HDMI Upconversion, so you can input your analog video sources and output them digitally via HDMI. This means that you will need only one HDMI cable to connect to your TV.
      • BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35% (available on Pioneer VSX-831 only).
      • HDCP 2.2 Copy Protection: Both receivers are HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
      • 3D Ready: Both receivers are able to pass 3D video through HDMI.

      HDR (High Dynamic Range)

      Onkyo TX-NR626 does not support HDR.

      Pioneer VSX-831 supports HDR10 and Dolby Vision. High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.
