      6. Amplifier

      Denon AVR-X550BT Onkyo TX-NR545

      5 channel Amplifier: Denon AVR-X550BT features 5 channel power amplifier. It is rated at 70 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

      7 channel Amplifier: Onkyo TX-NR545 features 7 channel power amplifier. It is rated at 65 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).
      • WRAT (Wide Range Amp Technology): Onkyo TX-NR545 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.
