Worth the $$$$'s
I upgraded from the 8802a and enjoy this unit (8805a just as much and more with added listening modes. Sound stage and quality are excellent. Built like a tank and easy on the eyes. I love the flexibility in configuring the speakers and assignable amps. I use all 13 channels and it sounds awesome. I would have give an overall 5 star except the HDMI sync/handshake is not always reliable with my Epson Projector when using PC as the source when streaming music. It will keep trying to connect until it finally does after about 4-5 minutes sometimes. Other HDMI sources connect first shot.

Great build quality, fidelity and over all feel!
Hello all, I purchased my Marantz AV8805A Nov 2021 after doing some extensive research on AV processors. My previous receiver was an SR5008. An old geezer but worked like a champ. This time I elected for AV separates in order to achieve higher amplification and better quality of sound. These can be achieved by separating components. In addition to the AV8805A I purchased a Marantz MM8077 to power my 4x Dolby Atmos ceiling speakers and a Parasound Halo A51 to power my 5x floor speakers. What I like about the AV8805A: build quality, overall feel, sound quality, connectivity options, user interface (UI, and app. What I don't like or is lacking on the AV8805A: online steaming capabilities, which I am finding occupy most of my listening time! I wish the AV8805A was a Tidal and Spotify Connect, AND Roon Ready (not just Tested). That would be huge! Yes, in some instances switching inputs will result in a loss of image or data to the TV (like previous comment mentioned). That is annoying, but I understand its complicated. This is happening on my Sony XBR TV. Remote control backlight should be brighter for night viewing and include text not just blank button. Its very hard to read at night. Also, let’s get rid of Audyssey XT32 and move to DIRAC, which I believe is far more superior to Audyssey (sorry Audyssey...). Took me 2-3 tries to calibrate my 5.1.4 speaker system even though I bought the Audyssey iPad APP. Its just not that reliable or accurate especially for low freq calibration (subwoofers). Another item on the wish list, perhaps another 1-2 8K HDMI inputs along with 2x eARC HDMI outputs. Overall, I am very happy with my AV8805A and would recommend it to others with few disclaimers. For example, I am back on the market for a good network streamer that can provide me with a higher quality streaming (32bit / 768Khz as opposed to current wired 24Bit/192Khz or 16Bit/ 44Khz on Airplay or Chromecast), and a Roon Ready, Tidal Connect, Qobuz and Spotify Connect native! These should really be included on a $5K AV processor... Thanks for reading this review. Hope you found it helpful.

Profound regret: loses hdmi sync with input device
I upgraded from an AV7703 in an 11.2 setup to a AV8805A in a 13.2 setup. My input devices are Apple TV 4K, Tivo Edge 4K, and of course ARC from a Samsung 8-series 82" LED TV. The AV7703 worked great in this setup. The AV8805A regularly loses sync with the input HDMI signal, at which time video and audio drop out. Recovering requires switching inputs or toggling power. This happens when the video mode changes, such as when returning to a Home Menu from streaming. Profoundly disappointing for such an expensive model.
