The only way of actually "providing more power" to a speaker is to play it louder so that more power is actually used. If for example 5 watts are being used at a particular instant in time, simply connecting a 100 watt or 1000 watt amplifier instead of one having a 10 watt rating doesn't give it a watt more of power.
Edit: the volume wasn't "the exact same" if the setting on the volume control was unchanged, since the gain of the Parasound was different than that of the internal Integra amplifier. Slight differences in loudness can be misinterpreted as a qualitative rather than a quantitative difference. This is why in blind listening tests one basic requirement is that volume be matched to within 0.1dB.
