i would have the concern that if it only makes the noise when you push the receiver to be loud. to me that would bring the worry that it's something to do with the power supply and or clipping on the amplifier section. As you have pointed out, this is not a higher end receiver so it can be that the specs on the amount of watts it can handle may be optimistically overstated.
