Powering my Magnepan 3.0's


I bought a pair of Factory refurbished 3.0's knowing they needed a shit load of power. I bought a Carver 1200 Watt M1.5t Mangnetic Field Amplifier. 600 RMS Watts per channel. Max of 750 Watts a channel not to exceed 1200 watts total output. I also connected a 150 watt Yamaha Subwoofer because I needed more bass. If I turn my Carver Pre-amp above 4.5 in volume (scale 0-10), my amp overheats and turns off, if I run the amp at slightly less then 4.5 volume in for about 1 1/2 hours, it also overheats. My question is: Do I really need more power? I imagine that the answer is yes but I was just checking with someone more knowledgable then myself. Should I get another m1.5T and bi-amp them? Thank you in advance for answering this question.

While the Carver amp is able to deliver enormous power short-term, it doesn't have the heat-sink area necessary to deliver high output long-term, so it's going into thermal shut-down. At least that's my guess.

I peddle the InnerSound amp, and it's a pretty rugged little beast. It's stable into a .3 ohm load, and it should be quite capable of driving your Maggies. I have several customers who drive Maggies (and worse) with their InnerSounds, and so far no one has managed to blow up their amp. If you get a used ESL amp, try to get either a Mk II, or an amp delivered since January 2002. Those dating later than January 2002 have a minor circuitry upgrade that makes 'em sound better - the upgrade is of course also incorporated in the Mk II amps, but was actually introduced a bit before the Mk II designation was introduced.

Best of luck to you!
