Onkyo TX-NR636 7.2-Channel Network Receiver
Onkyo receivers tend to offers lots of features, cutting-edge technology, and performance for the price. The TX-NR636 replaces last year's excellent TX-NR626, adding several new features while maintaining the elements that made the previous model so good. Like last year's model, the TX-NR636 includes a phono input, a feature usually found on high-end or boutique receivers, and could easily be the determining factor for a potential buyer in this price range.
As with the TX-NR626, the TX-NR636 comes with a Marvell Qdeo video processor for upscaling content to 4K; however, the TX-NR636 also includes HDMI 2.0 inputs allowing the receiver to support 4K/60Hz. This is one of the first receivers available to include this upgrade, making it an excellent choice for those who want to future-proof their setup. Fully gapless playback compatibility is also new this year.
The TX-NR636 has received a slight bump in power with 115 watts per channel while the 7.2-channel setup means the ability to hook up two subwoofers for extra bass. Built-in WiFi and Bluetooth are included, as well as plenty of internet radio/streaming options, DLNA certification, and MHL compatibility; AirPlay is, once again, not supported.
Sound output is excellent, and setup is a rather simple, but lengthy, process. Audyssey MultiEQ has been replaced with AccuEQ, which seems to also work quite well. Powered second-zone support is also included. Connectivity is good, with seven total HDMI inputs (six rear, one front), three composite inputs and a single composite output, and one component video in and out.
