The longer I wait for the new EA iamp 800 to come out (been waiting since February!), the more I'm starting to look at the possibility of going with a power amp and pre amp of some sort as an option for when my Clarus isn't enough to cut the louder gigs. After doing a lot of reading, I've narrowed my choices down to one of the QSC PLX series amps, or one of the Stewart World series amps. My "Headroom/Overkill" question has to do with the fact that I've never really understood the whole "Stereo/Mono/Bridgedandathowmanyohms" issue, and some of the power ratings on these amps look absolutely ridiculous on paper. I'm looking for an amp that I can use for both my DB and BG running through an EA CXL112 and a Bergantino HT112 (Both 8 ohm). It would be nice to run the amp so that I could tweak each side to balance the speakers, but not essential. So, the question becomes, how much wattage do I need to have to have plenty of "Headroom" in reserve without buying a system that has so much power that the speakers I'm using can never handle the power anyway? Please enlighten this technically challenged customer!
