Thanks Phil and others I think I've got a better understanding of what's going on there.
Actually I understand the Wiki article just fine. I derived the theorem in 2nd year EE and have an MSEE. It's covered in every Circuits 101 class. Actually I think opaq is a little confused about what it says because the reason the theorem doesn't apply for my question wasn't due to the parts about power transfer or efficiency. Of course thankfully others stepped up with very good clear-headed explanations as to what was going on. Thanks to Phil and others for that. There were some very good replies. As far as needing 400 watts. I have inefficient speakers. Aerial 7Bs (rated 86 dB but measured less in Stereophile). They drop to 4 ohms in the bass region. I thought about getting an MC252 but the MC402 was reommended for my speakers. But probably either one would work. Follow the old adage for cars - get the biggest engine you can in the model you want to buy. :) I've owned a 400 watt Krell and a 300 watt Musical Fidelity with these speakers and, yeah, they could get loud but I don't think they were overkill by any means. Also of course it has to do with delivering peak power when it's needed. Certainly the Aerials swallow the 100 watt Marantz I have hooked up to them now. It'll get loud too but you can tell they need something with more power or ability to deliver power when needed. Also nothing meant against Sean by quoting that link. No need for me to go and re-explain the theorem when a link would do. I was looking for a little more explanation and others nicely stepped up. regards, David -- wireless200 ------------------------------------------------------------------------ wireless200's Profile: http://forums.slimdevices.com/member.php?userid=11887 View this thread: http://forums.slimdevices.com/showthread.php?t=46347 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
