Ronnie, that "high instantaneous current" spec isn't especially meaningful. The key word is "instantaneous", meaning an instant maybe a few millionths of a second long. The amperage needed for a given amount of power is described by Ohm's Law, one form of which is P=VxI(power in watts equals volts times amps). Home receiver/amplifiers operate in the area of 30-40 volts(the 120V from the wall outlet is stepped down about 3 or 4 by the transformer in the power supply section of the receiver). Speakers use about one watt at a comfortably loud average level and if a brief peak called for 100 watts the amperage required would only be about 3 amps(P=VxI, 100=33.3x3). Gene DellaSala's
comments about "higher current" in his "misconceptions" section may be of interest.
So, don't be overly concerned with current ratings. If a receiver can supply a certain amount of power that means that it's also supplying the current required for that power.
