Hi I've got a wee question regarding 'impedance' - Thinking of buying the Eltax Camarque range but finding the right av amp seems a problem. Centre speaker = Impedance 4 Ohm Front Speakers = Impedance 4 Ohm Rear Speakers = Impedance 6 Ohm Was hoping to link this to a Marantz SR5200 but it seems the amp is running at 8 Ohm - I take it one or the other will blow up eventually. Have been recommended the Sherwood R956R by the bloke at RS as i've been told it will work with the speakers. I know you guys know better - he just wants his sale.... What should i do? HELP?
