It’s been several years, but had great success with a couple of items purchased through A4L No problems, prompt shipping, etc.
I am considering going for the refurbished AV7706 .
My only concern with that particular model has to with an upgrade several Denon & Marantz products received in May 2021.The HDMI 2.1 chip upgrade.
Apparently, 7706 models with a S/N of ********* 70001 or higher, incorporate the change and it would be installed in all affected Marantz & Denon products after May 2021.
So I have to wonder if any pre-June 2021 refurbs being sold include the chip upgrade. I guess I could also ask for them to verify the S/N.
