In general, you don't have to worry about pairing receivers with speakers. Most of the home theater AVR's are compatible with the vast majority of speakers out there. It's when you get into specialty receivers (usually meant for specific speaker packages) then compatibility issues may crop up like the speaker and AVR ohm rating.
The other aspect where you might need to be concerned when it comes to the speakers and the AVR you are pairing together, the power handling of the AVR can be important because if the receiver doesn't have enough power to drive your speakers at the desired volume level, you risk clipping the AVR which can damage the speakers. This is why some people on these message boards don't recommend Sony....their Amplifier sections oftentimes don't have enough power for high volume play when using 5+ speakers. Although this can easily be checked by downloading the manual and looking at the total power consumption of the receiver. Divide that amount by the number of speakers you intend to drive and that will give you the max amount of power (in watts) the receiver will be able to commit with all your channels being driven simultaneously.
For example, the Sony DN-1040 you want has a listed power rating of 120w per channel. However, that's for 2-channel (stereo) content. It has a general power rating of 100w per channel and it lists a "Surround" power rating of 165w per channel. However, the total power consumption of the entire unit is only 240 watts. That means at any given time, it can only divide that total power between all channels driven. Thus, if only using a stereo configuration, it can provide 120 watts to each of the channels. In a surround configuration, lets say 5.1, driving 5 channels, it can provide a maximum of 48 watts per channel. Granted, during most surround content, not all of your channels will be driven heavily during the movie. Usually it's just the front and center channels being driven heavily (fronts usually handling music/sountrack and center handling dialogue and centrally located sound effects) and the surrounds are used for ambiance type effects. The surrounds thus, aren't going to require a ton of power to drive during most films. however
, there can be times during some films, especially action/sci-fi films where all the channels are being heavily driven. During these moments, your AVR will be overworked and unable to provide all the speakers with the necessary power and it will clip, which is what you want to avoid, otherwise you could damage your speakers tweeters.
This is why a lot of folks around here don't recommend the Sony AVR's. They don't have enough power to drive a lot of speakers to reference level. I found this out from personal experience using a Sony AVR and finding my speakers starved for power when I increased the volume (it could barely handle 40 watts per channel driving 5 speakers) so I went with a Denon AVR that has a total power consumption of 490 watts that gives my setup at home 98 watts per channel to drive my speakers. More than enough for my purposes.
