Looking for info on speaker loads?


I am running the integrated amp: NAD M33 and recently changed speakers. 

From KEF LS50's to Magnepan LRS.

For the first time ever I'm getting a warning that my right amp is over heating. As I go up in volume, a tad higher than normal listening levels but no where near ear splitting levels. 

I emailed NAD and they said the M33 can run the Maggies mw/o issue.

The speakers now and before have REL t/5i tried to them, the music is nothing hard to reproduce i.e. Sam Cooke coming off of Bluesound Vault ripped CD's.

The forum members here have much more experience then I do and was hoping to get some help, insight to solve the problem or at the least understand the problem, of course I've heard often that the Maggies are hard to drive.

maggies would draw more current than the kef's... perhaps your m33 has a bad output module (or at least a bad warning circuit sensor...)

FWIW I had a Parasound A21 pushing Magnepan MMG's. The amp never clipped but as I pushed the volume up I could almost feel the current draw on the amp. With the other two speakers I have, one pair is 8 ohm and the other pair is 4 ohm i never felt that the amp was pushed hard..... and the speakers would be LOUD.

The advice from russ69 will allow you to narrow down the problem... for sure. But i am willing to bet you the Maggies are dipping and your amp is straining.

I had the LRS for a bit. I had a McIntosh 452 amp that had no trouble with other speakers. I felt like the Maggies were just ridiculous with the amount of power required. Great $700 speaker that requires crazy power. Your story doesn’t surprise me.
