I would like to upgrade my 4-year-old 7 channel Yamaha RX-A770BL 4k AVR to a HDMI 2.1 capable 9 channel AVR to be the heart of my home theater system which includes the Sony 83A90J, Panasonic UB9000 BD player, and Definitive Technology 9.2 speaker system. I am trying to keep my budget below $2,500. I am doing my due diligence research on Yamaha A6A, Denon 4700, and the Onkyo TX-RZ50. All three have great capabilities but unfortunately are not yet available in my area to hear in person, so I am left with evaluating specs. Here is what I have found:
Onkyo TX-RZ50- Retailing at $1,399, I am very impressed with the value and capabilities offered by the 2021 Onkyo RZ50 with (7) 4k/120hz HDMI 2.1 inputs and 2 outputs, Sonos compatibility (I have Sonos eco system), Imax enhanced, THX certified, and Dirac for $1,399. The drawback I see with the RZ50 is that both sub channels are mono, and I prefer two discrete channels. I was also hoping to include Auro 3D. I think an additional risk to consider could be how the new company survives and reliability of the RZ50.
Denon X4700H – Retailing at $1,999, the 2020 model of the 4700H is impressive and supposedly has the 2020 HDMI issues resolved with units manufactured after May 2021. It does have Audyssey MultiEQ XT32, discrete sub channels, Imax Enhanced and Auro 3D. The drawback for me is only one 4k/120hz HDMI 2.1 capable input. But that stated, I only need one at this time for an Xbox Series X. I understand Denon offers an adapter switch that permits 3 additional ports for an additional $200. I would consider the X3700, but it does not have Auro 3D capability. I do not have a sense of the Denon X4700H reliability.
Yamaha Aventage RX-A6A - Retailing at $2,199, this 2021 AVR is built like a tank. It has incredible build quality and performance specs. I have been very impressed with my current Aventage RX-A770BL which sounds great and has been very reliable. The A6A has discrete sub channels, Auro 3D and (7) 4k/120hx HDMI 2.1 inputs with a future firmware update. It does not have Imax Enhanced. I do not like the accuracy of the single position YPAO calibration on my RX-A770 and I am not sure how the new YPAO -RSC 3D multi-position calibration system on the RX-A6A will improve. That is a risk to me over the Denon XT-32 and Onkyo Dirac.
To summarize, frankly, I could go with either of the 3 AVR’s. The Yamaha A6A checks all my boxes except Imax Enhanced and the uncertain new YPAO -RSC 3D multi-position calibration system. Regarding the Onkyo RZ50, I am not sure how big a deal it is having two mono sub channels vice 2 discrete channels – which I currently have, and not having Auro 3D, but I am intrigued by Dirac. The Denon X4700H checks most of my boxes with XT-32, but unknown reliability and a single HDMI 2.1 output.
I would appreciate any thoughts or comments from Yamaha, Denon or Onkyo owners.
