I don't really think in terms of quality among Onkyo/Yamaha/Denon/Pioneer/HK etc you are really going to notice a big difference. It just seems whatever offers the best options for you and whatever you can get the best deal on is the way to go. If you can get a fully warrantied new old stock Denon for a great price I don't know why you would keep looking elsewhere, as long as it does everything you need/want it to do.
