Hi. I've had one of these for about 2 weeks now and im throughly impressed by the sound quality compared to my previous seperates. I have a pair of Eltax Jupiter 5 speakers which I am considering swapping with the current pioneer speakers. Now I know that the Pioneer has quite a hefty output, but I want to know if the eltax speakers will damage the amplifying stage on the receiver. The impedence on the eltax speakers is 4-8 ohms and the power is: "Music Power - 90 Watt Sinus Power - 60 Watt" TIA.
