how much power

'As to 150 watts and 45 amps? That's about 3.3 volts. Clearly something doesn't add up.
My panels are fused at 4 amps for mid/tweet. Figure 8 amps full tilt for the whole enchilada. Why would I need 45 amps?'

Well what does it all mean? Some very reputable companies always list this spec. Parasound and Harman Kardon come to mind. The bigger HK list 100 amps and the parasounds 60 amps. I have read some gurus that say amps are not even important. So I guess it's an audiophile thingy, i.e No answer. BTW, the link and the cube graphs etc.... are very similar to the method used to test amps in the Audio Critic. Better be careful. :)

What is the minimum amout of current an amp has to deliver, to be considered a 'high current' amp?

Marakanetz:

my amp is rated at 150 wpc and 45 amps per channel. my speakers are 88db 4 ohm. Is this a good match? Smallish room and modertae levels, so I have no complaints, just curious.

'What is necessary for amplifier to deliver the same power onto the 4Ohm load vs. 8Ohms is to double the current and not on peak or transient bases but on continous.'

Then, would it be accurate to say that a true 'high current' amp will double the current (continous) when the load is halved?
What, if anything, does this say about the quality of an amp? I am trying to decide between the Harman Kardon HK 990 and the Parasound New Classic 2250. The HK doubles, the Parasound does not, but it's watts per channel is greater into 4 & 8 than the HK. The parasound list 45 amps and the HK 100amps. From just this information, can any conclusions be drawn as to which is the better quality amp?
BTW, thanks for your answer.
