Onkyo TX-NR646 review

 

It is written in the AV bible that the industry "shalt invent a new doohickey every year that compels the buying public to back its wallets up to the till and empty the contents on new gear." Last year that doohickey was Dolby Atmos ; this year it's...

The fully-loaded Onkyo TX-NR646 delivers cutting-edge technologies such as both Dolby Atmos and DTS-X surround formats, in addition to AirPlay, Wi-Fi and Bluetooth. Its sound quality is excellent for movie replay with exciting sonics and class-leading...

The Onkyo TX-NR646's Dolby Atmos height channel capabilities are limited to only the front-left and -right channels, not the surround height channels, and the receiver is only DTS:X "compatible" until an update is released later in 2015. Its external...

Considering the Onkyo TX-NR646's generous feature set and superlative sonic skills, it's one heck of a value.

Onkyo TX-NR646 and TX-NR747 Atmos / DTS:X AV Receivers Preview

 

Onkyo's TX-NR646 and TX-NR747 AV receivers are among the FIRST DTS:X receivers on a manufacturers website. Dolby Atmos and DTS:X ready as well as having 4k Ultra HD, Bluetooth and Wi-Fi. Upgrade time?

Consumer review (cnet.com)

Great name, great value!

 

Comparing to different brand items, at similar cost, this thing blows them out of the water! I've tested Dennon, Marantz, and Yamaha within +200$ of this price range, and I really felt this one will get you the best bang for your buck. Tons of HDMI...

Power, Inputs.

Jaw dropping performance and at insane price

 

This replaced a $2500 Arcam receiver that was 11 yrs old and my only regret is the Arcam didn't break sooner.

Sound and Video quality is superb. Power is impressive. Switching is fast.

Zone 2 will only send out an analog source. So I connected a zone 2 speaker to the center channel for dialog to hear tv in the other room.

Onkyo's Rock!

 

Onkyo has been building electronics since the early 40's, and nobody puts power supplies, transformers or heat-sinks like they do.

The sound and power from Onkyo is crystal clear and raw. This is the third A/V receiver I have had. The first was purchased in Circuit City's infancy and gave me many, many hours, but had no HDMI ports. I have a TX-NR709 that developed a sound problem....
