All easy 8 ohm loads. The receiver doesn't get hot to the touch at all and like I said it's fine in 5.1.
Don't bank on it being an 8 ohm load. Tell us what your speakers are and I will tell you if it could possibly be an 8 ohm load.
I pointed out this very week, that a speaker rated as 8 ohm by the manufacturer as 8 ohm, was clearly 4 ohm. I was able to look at the specs of the drivers involved from the OEM driver manufacturers sites. This proved to me the speakers had to be four ohm or less. The speaker manufacturer admitted yesterday, in these very forums, that the speakers were four ohm.
Most towers are 4 ohm, no matter what the manufacturer calls them. A lot of diffraction compensated book shelves are also less than 8 ohms, even though rated at 8 ohms.
After looking dispassionately at manufacturers "nominal" impedance ratings, I have come to the conclusion that they are meaningless. They are stated to be 8 ohms no matter what the facts really are, in order not to loose sales from receiver owners.
However I really fault the receiver manufacturers for this. I see little point turning out devices that will not comfortably drive four ohm loads.
