I would like to hook up a pair of EX speakers, my receiver has 125x5 watts it also has NON powerd out puts for EX speakers,how much amp do i need to run a pair of klipsch surround speakers , i see all kind of power amps on ebay and audiogon, c city has a onkyo 282 amp 100x2 for $299.00 you can buy a 50 x2 for 199.00 at best buy,im just not sure what to do, i dont think EX speakers get that much info from a dvd to need a really $$$ amp, does anyone have any ideas what i could use.
