Yes, I'm currently running my M80s through a vintage A\B pro power amp.{Crest Audio VS900}circa 1997 450 watt dual 900 bridged. When I first added it the difference was noticeable more bass and a lot more to the volume. My receiver set them to full range and I didn't even check for a couple months, until I noticed my little SVS PB1000 sub was inaudible the M80s were doing all the work with out any strain.
I suspect with an ADA your larger speakers could run full range easily. Though to reenact the commercial you'll probably have to sit in front of your Ep800 at some pretty high volumes.
The Monster cables can be found on sale quite often as most shops like to turn their supplies, especially in larger cities. But I bet that FosPower cable will do just fine, it was just easier for me to get the monster cables my self as I've got a shop a couple blocks away.
