Thanks Alan. I've only been to the soundstage.com site a few thousand times. It seems to have the most comprehensive collection of anechoic measurements around.

It's a complicated site to navigate. It always takes me forever to find the measurements page. I'll post the link if I figure it out. . .

Hi,

OK, here's the link to the M80 v2 measurements and impedance curve:

http://www.soundstagenetwork.com/measurements/axiom_m80v2/

If you just go to http://www.soundstagenetwork.com/measurements you can access all the NRC speaker graphs for speakers that Soundstage has measured at the NRC.

Regards,
Alan

wow... I was really thinking it would be good to buy one of these XPA2's also. And to think audioholics gave it such a rave review... hmmmmm.

oh well, I need to buy an ep-800 first anyway... and a diamond ring before that.

The other alternative is to look for a good used amp on Audiogon.

You can usually find good deals on Acurus (A250 or A200X3) or ATI
AMPS there. I've had both brands and they never shut down on me.

Actually, he used 4 2 channel Parasound Halos. Of course, he was regularly driving them to 115 dB+

Thanks, Ken.

You actually experienced his setup and the 115-dB-plus SPLs, right? I had running communications with Denis as he went through various combinations of multichannel amplifiers.

It is intresting to look at the different measurements. The M22 which no one appears to ever have an issue driving, has a pronounced dip to 2 ohms, so much for my theory.

Does the high-current-draw-shutting-down-the-amplifier problem have anything to do with the fact that the electrical wiring in my home I'm pretty sure is not rated to handle the current being drawn? If I upgrade the wiring to 1 or 2 dedicated 20 amp lines, might that solve the problem? It doesn't make sense to me that it would except through some kind of instability phenomenon, e.g., when I plug the amp directly into the wall and presumably even more power is available it almost seems to cut out faster. I may need to upgrade the wiring anyway given the load I am already running and what with the ep800 on the way, but I was just wondering if there was any theoretical reason to expect that it might help.
