The Onkyo TX-NR636 - REVIEW | AV Product Reviews
AV Tech Reviews Staff | On 21, Mar 2014
AV manufacturers are slowly starting to unveil their receiver offerings for 2014. Pioneer’s announced new entries in their VSX line of receivers and now Onkyo is doing the same by announcing their new Onkyo TX-NR636.
Onkyo has always been a forward thinking manufacturer and with the 636, Onkyo has cast their eye towards emerging 4K technology. The Onkyo TX-NR636 supports 4K/60 Hz and offers Ultra HD upscaling via HDMI. The 636 also supports the latest DRM copy protection and is HDCP 2.2 compliant. Like last years Onkyo 626, the 636 is both bluetooth and WiFi compliant.
MP3 audio files have been the audio standard for years. However, in recent years HD audio has begun gathering a larger and larger audience. The Onkyo 636 will support a number of HD audio formats including; Double DSD, FLAC and ALAC. Even old school vinyl lovers will have something to cheer about since the 636 also includes a phono input.
The one thing that is curious about the Onkyo TX-NR636 is its lack of Audyssey calibration. Instead the 636 utilizes Onkyo’s proprietary AccuEQ calibration system. Onkyo’s been using Audyssey’s highly respected calibration system for years so it’s a little surprising to see that they’ve abandoned it in this years 636. We’re eager to get a review copy in hand to see if the AccuEQ is capable of delivering the goods.
