Hi,
I avoid reviews that are very subjective. Until unless someone shows the technical testing and the results, I stay away from them. In general all reviews are geared towards convincing a customer to buy the product. many times they are paid reviews.
I typically use Denon receivers almost all the time for installations, as they give best value for money to the customer (not the dealer).
Based on your budget you can go with AVR-1912, AVR-2112 or AVR-2312.
Audio processor, Audyssey calibration gets better in the higher models.
Here is a comparison chart for the receivers

Room has significant affect on the audio performance. Audyssey calibration will help a lot. Monitor audio speakers are fine if budget is a concern.
If you are using Oppo BDP-93, set the video output (HDMI1) to RGB, 36-bits.
Let me know if you need anything else.
Thanks
