Denon AVR-X1400H vs Onkyo TX-NR646

Onkyo TX-NR646 review

The gadgets are quite similar. They both have 7.2 channels, but the output power is bigger in Onkyo: 160W against 120W at 6-ohm load. Onkyo TX-NR646 impresses with its widest functionality, as it has as many as eight HDMI inputs with support for HDCP 2.2, for 4K video, and two HDMI outputs, thanks to which you can watch movies in two different rooms. In order to fully enjoy the capabilities of the amplifier, the Onkyo TX-NR646 receiver has eight analog audio inputs and two parallel audio outputs for subwoofers, as well as a USB connector for connecting any device with media files.

Denon AVR-X1400H review

The control system has a simplified setup interface, but its sound digital path is advanced: a quad-core 32-bit processor with all the necessary decoders, the ability to work with wireless connections (Bluetooth, Wi-Fi), the standard Audyssey MultEQ XT auto calibration system using a remote microphone, and quite developed for an inexpensive model bass manager. Which, in particular, allows you to set not only different multichannel configurations and flexibly change the assignments of the sixth and seventh channels, but to vary the filter settings for each speaker over a wide range, precisely set the distances and corrections.
