Mostly Satisfied with Some Letdowns

Upgrading from a Yamaha RXA-870 to gain 11.2 surround with ATMOS, this receiver offers extensive control but lacks the superior web app for surround sound management and is more automated. Speaker calibration repeatedly reports a wiring problem with the right speaker even when nothing is wrong. Software updates take about 45 minutes via USB and work without issue, though slower than hoped. The unit is very heavy and requires help to place on a shelf, which must be heavy duty.

Pros
  • + extensive control
  • + ATMOS with 11.2 surround
  • + software update works without issue
Cons
  • − lacks superior web app for surround sound
  • − more automated
  • − false wiring problem message during calibration
  • − slow software update
  • − very heavy

Unit Failed, Warranty Uncertain

The unit stopped powering on and shows a blinking red light after less than two years of use. Yamaha is verifying whether the third-party seller is an authorized dealer before approving a repair. The product listing advertises a five-year warranty with registration, but it is unclear whether the seller qualifies. The outcome of the warranty claim is still pending.

Cons
  • − Unit failed to power on
  • − Blinking red light
  • − Warranty coverage uncertain
  • − Third-party seller authorization unclear

Powerful upgrade with independent subwoofer control

This receiver is a powerful upgrade for a home theater, moving from an A4A to a 5.2.4 setup. Independent subwoofer adjustment makes a big difference in balancing sound. Paired with an Emotiva BasX A3 to relieve the front stage, the setup is highly dynamic. A Denon 6700 was tried but not liked. The backlit remote lights up when picked up, and pass-through works well, allowing attached devices to be used with headphones or TV speakers while the unit is off without waking others.

Pros
  • + independent subwoofer adjustment
  • + dynamic performance with external amplifier
  • + backlit remote
  • + pass-through works well
Cons
  • − Denon 6700 not liked
