How To Measure "Current" In An Amplifier?


.
I've heard lots of times that an amplifier needs lots of "current" to drive a low impedance load.  
Is there any measurement on a spec sheet that would measure current?  
A high watts per channel amp does not necessarily mean that the amp has high current.

Thanks Almarg. Understood. And Ralph's explanation was a bit "over-my-head". :)

Erik, in answer to your question, Musical Fidelity M6si amp and Golden Ear Triton One speakers. 
Ahhhh.....

The GE Tritons are electrically and acoustically complicated beasties and exactly the kind of speaker design I've learned to avoid. Make yourself happy of course, though.

As for the amp, I would say that since they are excluding 4 ohm measurements and damping factor they are not particularly proud of it's output into low impedances.

Not the best match, surely.

Erik, just as a point of info the M6si manual indicates a damping factor of 180.

I’ll mention also that once damping factor gets above say a few tens (in other words, away from tube amp territory) I would not expect much if any correlation between damping factor and performance into low impedances.

It's worth pointing out though that damping factor is not just one number. It can rise considerably in higher frequencies, where the Triton has oddly low impedance numbers.

AMT tweeters do not inherently have low impedance by the way. Cheap one's do. :)

Best,

Erik
