"High Current"

I listen with my ears, and I dont really often care about the mathmatical conclusions but I have a friend who argued with me that Current cannot increase without wattage increasing as a result. I understand the simple formula is Voltage x Current = Wattage or something to that effect, it's been awhile since I openned a book.

How then can an amplifier from say a company like SimAudio which has a nortriously high current intergrated in the i-5 be only rated at 70 watts per channel?

Is it the differences which the current, voltage and wattage measured that makes the overall impact or can you really have an Ultra High current amp at a very modest Wattage output?

Sean, IS it possible to manufacture an amp for home use that doubles down at clipping to, say, 2ohms??
I'm not sure, but i think it's theoretically very dificult?
Cheers

With all due respect to all, what Sean is saying is hardly revolutionary -- and thereby, hardly controversial. All he's describing is an amp where the manufacturer is (truthfully) saying: "this amp is stable down to 2ohms and I guarantee that at that (resistive) load this amp will produce 1200W of energy; similarly, it will produce 600W if the load is 4ohm and 300W if the load is 8ohm".
What said manufacturer did NOT openly claim is that these are peak power/ energy ratings before clipping.
All SEAN is saying is that one shouldn't construe these specs as such. Some manufacturers may be refering to peak W at clipping while others NOT: I.e., what the manufacturer COULD be saying is "this amp will put out a MAX of 1200W at 2ohms, well over 600W at 4ohms, and substantially over 300W at 8ohms".

In the old times some manufacturers were even proud of quoting stability at 1ohm to show how well their product had been implemented.
