Low(ish) budget receivers with pre-outs?

Sorry I wasn’t being clear. The receiver would be used to input my Apple TV and DVD player via hdmi and output the video to my projector and output the audio to my speakers

Receiver would essentially be used to add HDMI’s into the mix 

good tip on the ohm’s stuff. Would the receiver still need to power 4 ohms even if the external preamp and amp setup are the ones that are powering the speakers? Sorry if that’s a dumb question 

Good call! I’ll look into hdmi switchers 

The audio out port on my benq 2050a projector is just a standard 3.5mm aux jack. Running my systen directly through that port would destroy sound quality right? I guess that’s why I was looking into receivers in the first place
