My two cents worth:
TL;DR: Like the Onkyo receivers and Aperion speakers

I bought an Onkyo TXNR-1008 in February of 2011 and absolutely loved it. We used it at least 10 hours a day listening to music and watching either TV or movies. Also, we had it in an enclosed console with bottom vents, glass shelves and dual cooling fans with a temperature switch in the cabinet. About six months later we started having trouble with it. The receiver started to scroll through all of the different listening modes. After resetting it by unplugging it for an hour, it was fine for about a day, and then started scrolling through the speaker selections. Onkyo repaired it with no charge and it worked just fine for five years, but we moved the blue-ray player out of the cabinet and the receiver was the only piece of equipment in the cabinet. In late 2015, we started having more problems. CRS has kicked in and I don't recall what it was, but I think it was a lost channel. I looked on-line and the 1009 had the same problem that Onkyo was repairing at no cost, but I wanted an upgrade to the Dolby Atmos and used the opportunity to by a new receiver. We got a TXNR-3030 and placed in on top of the cabinet instead of inside. So far there have been no problems and both my wife and I are still very happy with it. It also gets used at least 10 hours a day.
The speakers we bought from Aperion Audio. They are made in the USA and have something to fit practically any budget except very to extreme high-end. We got the Verus Grand towers and center channels, one Bravus 10" sub and in-ceiling speakers for the back and rear speakers, making it a 7.1 system. Again, we are very happy with them. I installed the in-ceiling speakers myself, as they are located in a 1978 era "Great room" with a cathedral ceiling. One side is open to the attic and the other is right under the roof. It was easy to fish the wire down to the holes cut for the speakers. Make sure you run wire rated for in-wall service. To date we have not updated with the extra speakers for the Atmos to operate. I'm leaving that for an actual media room that I hope is in the future.
