Hello -
I've been interested in an amplilfier to mate with my Harman Kardon AVR 7000. I sent in a question to tech support at Harman asking about the Signature 2.1 -- I mentioned that I had always heard that more amplification would provide better sound. However, in this case, since the AVR 7000 and the Signature 2.1 are both rated at 100x5 WPC, I was doubtful that there would be a performance gain.
He pointed out that the 2.1 had 100 amps, while the AVR had 75 amps. Even though they both have 100 watts.

The SIG 2.1 amplifier puts out 100 watts per each of the 5 channels @ 100 amps of current and the AVR7000 puts out 100 watts per channel @ 75 amps of current. There is a 25 amp difference, so of course the SIG 2.1 has more power,
I'm not sure if I understand this. Can someone help clarify? Watts are power, right? Then what's the deal with the amperes? Does he mean to say that the amplifier is more capable of driving higher loads? I'm just trying to draw a bead on the original issue: If an amplifier and a receiver are acurately rated at the same power rating, what performance benefit will there be?
