NAD 7400 power envelope vs. Arcam Alpha 10P

Setting up a modest two-channel system for music with some older gear which has been in storage. Wondering which amp is better suited to drive low impedance speakers like the Hales Revelation One's or Two's? A Stereophile review mentions of the Alpha 10P "Only into the punishing 1 ohm load, where the 1% THD limit was reached at 425W, did the power supply voltage droop to the point where no more significant power was available. But the peak current at this point was an astonishing 20.6A! The (Arcam) amplifiers are not really designed for very low impedance loads, and, given their limited heatsinking, are probably not the best choices for driving difficult loads."

By contrast, the spec sheet for the NAD 7400 power envelope receiver i recently acquired (basically a NAD 2400 amp) states peak current output of 40 amps. Both amplifiers are rated at 100 watts RMS. Opinions?
