So as noted in a earlier post a while back I came across a Yamaha DSP-A1000 AVR receiver that I like a lot. I do not see any mention of using 4ohm speakers with it in the owner's manual. When looking at the center channel connections (you can use two) it appears to mention using speakers with a minimum rating of 4 ohms. Nothing similar appears on the back. Do you think it is safe to assume this receiver could handle a 4ohm load for the front speakers???
