Auro 3D is a rarity, which is probably why Pioneer had eliminated the feature from their new A/V receivers because the lack of Auro 3D soundtracks being encoded on Blu-rays and 4K UHD. My Denon 4400H has Auro 3D and I've never utilized it, so I don't know what it sounds like.

Pioneer did not eliminate Auro 3D from their A/V receivers, Pioneer just never offered the feature when Denon and Yamaha started offering the feature. There are a few Auro 3D titles released in the United States, mostly on the Blu-ray Audio format which all Blu-ray players can play.

However when it comes to movies, Auro 3D has a limited selection especially in the United States when it comes to home video. Auro 3D can be used on the Blu-ray and 4K Blu-ray format with 7.1 PCM being the core audio. AuroMAx is 26.1 channels but Auro 13.1 is the most common version used at home. I created a thread on Auro 3D at the following link.

Pioneer Elite A/V receivers are very reliable A/V receivers and when connected to a good pure sine wave UPS they can last over 20+ years (same is true with some Yamaha A/V receivers). However, Pioneer is at least a notch below the quality of some of the latest high-end Denon and Yamaha A/V receivers that offer 13.2 channels with new features like Auro 3D.

Since movies in theaters use Auro 3D with 13.1 or 26.1 channels, I am hoping that 4K Blu-ray disc releases will use the technology. Auro 3D has 7.1 PCM core audio that a old 14 year old 7.1 channel A/V receiver is compatible with. Just consumers would need to own a Auro 3D A/V receiver to hear 13.1 or 26.1 channels. Over 200 movies in theaters have been released with Auro 3D, so those are the ones that could be ported over to 4K Blu-ray using the existing 7.1 channel PCM studio masters.
