My older AV pre-pro crashed and new models were in short supply. I bought a refurb Marantz AV 7706 from Accessories4us a week or so ago. I paid for fast shipping and expedited handling. It shipped the day I ordered it and arrived in two days. Looks brand new. Has the original factory stickers on it/was "fac-packed" (though gear slingers know how to do that). Came with 1 year factory warranty plus 2 years extended.
Now if only I could figure it out- talk about complex! I did get it working though and it looks and sounds great. This is for a modest 4k/5.1 home theatre set up in my front "parlor."
Marantz did acknowledge that they are a legit reseller. It isn’t just price- given the Covid/Supply Chain/Yada (I need to come up with a defined term for this), such devices, brand new, seem to be in short supply.
Good hunting.
