I'm trying to get a handle on how much power I really need to drive my pair of S15-Ds. They're rated at 200W RMS and 400W peak, but have a rep for taking whatever you throw at them. Theyre high efficiency, published at 103 dB. My current Carvin DCM1000 does the job well at 1000W bridged, which I've always been led to believe is a bit overrated - more like 750W from other manufacturers. I've been considering finding an iAMP-800 to demo, but am wondering if I could get by with an iAMP-350, a WT-400, or something like a WalkAbout. I don't slap, so my headroom needs are reasonable. I'm basically a glorified basement player, so my power needs are minimal. However, I want enough to effectively and efficiently drive my beloved Bags. I know each of these heads have a distinctly different sound, but Im going into this with no preconceived notions - I want my ears to decide. Maybe I'm just getting caught up in the chase (and advertising), but I find EA's claim that their iAMP-350 will do 350W all day long and 1200W peak to be quite intriguing. Wretched excess is fun, but if I can save money and weight by going with a smaller head, I'll be happy. Im going to try running my Bags off of one side of my Carvin for awhile, which will be 350W. However, Id like to hear what others have to say. The reason for all this? I'm sick of fiddlefarting with three separate gain controls on my current pre and poweramp rig! I want the simplicity of *one* master gain control. I really like the tone of my RBI, and have been considering a Landmark 600 or the new Landmark 300, but want to look at other lightweight heads, too.
