Features & Performance

Either Onkyo TX-NR686 or Denon AVRX2500 have the built-in Bluetooth and Wi-Fi, as well as the 4K upscaling to watch even the old content in high resolution. Both of the 7 channel devices have the same shortcoming – the lack of the ASR tech to hold files’ quality after their compression. However, they gladden with the Pure Direct mode to suppress interferences.

Connections & Setup

If to compare their capability, both units are dual-zoned but not three-zoned. Onkyo TX-NR686’s zone 2 is plenty of power for patio speakers. The comparison of the inputs is in Denon’s favor – it’s got 8 HDMI inputs versus Onkyo’s 7 ones for connecting more devices and getting the immersive sound.

The Denon’s equalizer provides the good sound from speaker to speaker. Both receivers have no MCACC Pro calibration that could make the settings easier. Onkyo’s Bluetooth makes impossible to connect the Bluetooth headphones directly to the AV.

Design

The test Denon AVRX2500 vs Onkyo TX-NR686 could not do without the comparison of the units’ dimensions. Onkyo is more massive, so make sure Onkyo will fit the space. Denon has 2 large buttons on the front panel (volume and source buttons), and Onkyo TX-NR686 has only 1 volume button on the right of the front panel.

Onkyo TX-NR686 Pros & Cons

Onkyo TX-NR686 PROS:

  • Access to the major streaming services – Deezer, Amazon Music, Spotify, and Tadal.
  • THX Certified that confirms the AV’s highest sound quality.

Onkyo TX-NR686 CONS:

  • The sound is too delicate with the lack of the dynamic range.

Denon AVRX2500 Pros & Cons

Denon AVRX2500 PROS:

  • The on-screen set-up menu takes through each step and it’s very easy.

Denon AVRX2500 CONS:
