Happy Father’s Day! I was picking up kids from an activity and happen to drive by a neighbour who dumped a pile of stuff on the curb, so I picked up the electronics you see here! A few months ago I missed an opportunity to grab an even better system with cassette decks because I was walking by another house and by the time I got home to get the car and pick up the stuff, it was already gone!
What I have is a Denon AVR-S730H. I know nothing about this, I have to research it. The other devices are just a 5–disc CD changer from Sony CDP-CE500, and an old JVC CD/DVD player XV-S30 with only composite output and S-video. There was another box which I grabbed with what look like 7 Google Home devices, a ton of cables and mounts that go with them (nice USB-C power collection). As a bonus, the CD player still had a couple of Elton John Greatest Hits CD’s in it!
As Dave would say… winner winner chicken dinner! Now what do I do with all this stuff before my wife kills me?

Can those Google Home devices be factory reset and re-used or do they get locked to the previous owners account? Are they still compatible
