Onkyo Warranty --Upgrade to Integra 5.4 offer due to lack of parts

[sfmarine]

So My RZ820 came with a 3 year warranty. I purchased it in 2019 as a leftover from Huppin's. The 820 debuted in 2017 and has 7 channels. One of my HDMI ports failed and I let it go for a while (because I was still able to use the other ports), but finally got around to contacting Onkyo. They no longer work out of New Jersey and most repairs are outsourced now. They provided me with a few local people in my region and I found someone with good reviews.

The tech told me it could be a while because of all the backorders and supply chain issues. After almost three months without a surround setup, I received a forwarded email today from Onkyo. They basically said that due to the abundance in part delays the parts are backlogged with no ETA.

However, they offered me a very attractive and tempting offer ...

To exchange my current unit with a refurbished Integra DRX 5.4 with an additional extended warranty. The Integra has 9 channels and came out last year, so this would be a pretty sweet upgrade. Not a fan of refurbished models, but this is direct from Onkyo and dealing with the source is always ideal.

I still prefer the clean look of the RZ series.

It still seems like the Integra is the way to go as it is currently one of their flagship models.

Especially considering my receiver is from '17 and was discontinued a while ago. It also means I’ll get my surround system back probably within a few weeks vs likely a year.
Thoughts?
