I am interested in the Jamo E805 bookshelves, but they are 4 ohm speakers. Would it be ok to use my Marantz sr8400 or my Onkyo HT-R510 receivers to drive the speakers? The receivers won't blow up will they? I know 6 ohms is ok, but I never had speakers rated at 4 ohms. The rest of my speakers are 8 ohms that will be connected to either receivers. Which of the two would you suggest me hooking up these speakers with no complications or does it matter since both are quality receivers? I posted this in the Speaker forum also, but would like some insights from the Receiver forum as well. LMK. Thanks!!!
