Yamaha lower end receivers, the RX-V571, RX-V671, and RX-A710 are really nice receivers beating most for performance and convenience features but the RX-V871, RX-A810, and RX-A1010 are poor values IMO. They offer subpar room correction and subpar upscaling next to the competition.
IMO, the AVR-3312CI has the best performance and convience features for it's price. Marantz should be close since these 2 receiver lines usually share a lot of design practices since they are owned by the same company D & M holdings. Denon usually comes out to be the better buy IMO and that's likely because Denon has a larger retail market from what I've seen.
I love the AVR-2312CI so far, it's sound is very good and judging by the Home Theater Mag review of the AVR-2311CI, it's power output is just slightly lower in multichannel and stereo, than the AVR-3312CI.
You do give up some convenience features and some performance features but so far I'm impressed for the low price this receiver is now going for. It's power output is as good as many $1000 - $1200 receivers.
I previously had an Onkyo TX-NR709 ordered and cancelled due to the problems people were having. My dealer was aware of the defects and couldn't promise me a unit that wouldn't be defective. I then later ordered the TX-NR609 thinking that these were defect free, only to find a major problem with these units as well, where Onkyo posted a statement on their website on how these receivers were defective and how they would be repaired. I cancelled as I have enough headaches in life, a toy should bring joy and not stress.
I have been using a Denon AVR-3803 that replaced a Defective Yamaha RX-V2300 I had ordered from Tweeter before they folded. The Denon has been great. I just ordered and setup a Yamaha RX-A710 which turned out to be defective, once again
, from defective video conversion, defective HDCP protection and a defective HDMI control handshake problem with my cable box. Sent back and bought the AVR-2312CI. It has none of the latter 2 problems but still has black level bug with analog 480i video conversion to HDMI. Seems this is the norm as both this receiver and the Yamaha had it, but I'm looking for a fix from Denon on it right now. BTW, before the defective RX-V2300, I had a defective RX-V596 that a home owner bought for an install I was doing. So the last 3 Yamaha receiver I bought were defective so I don't trust them much more and put them in the same reliability category as Onyko, POOR.
