      6. Amplifier

      Denon AVR-S540BT Onkyo TX-NR525

      5 channel Amplifier: Denon AVR-S540BT features 5 channel power amplifier. It is rated at 70 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

      5 channel Amplifier: Onkyo TX-NR525 features 5 channel power amplifier. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).
      • WRAT (Wide Range Amp Technology): Onkyo TX-NR525 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.

      8. HDMI

      Denon AVR-S540BT comes with 5 HDMI inputs. It has 1 output.

      Onkyo TX-NR525 comes with 6 HDMI inputs. It has 1 output.

      • 4K/60Hz Passthrough on Denon AVR-S540BT: All inputs pass up to 4K 50/60Hz 4:4:4 video signal.
        4K/30Hz Passthrough on Onkyo TX-NR525: All inputs pass up to 4K/30p video signal.
      • 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 Denon AVR-S540BT 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)

      Denon AVR-S540BT supports HDR10, Dolby Vision and Hybrid Log-Gamma.

      Onkyo TX-NR525 does not support HDR. 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.
