No Mo, that's exactly what the case is: an amplifier has to have both a power supply section and one or more channels of output transistors to measure out the required amount of power to each speaker. These receivers that have been discussed in relation to supposed "biamping" have only one power supply section and therefore only one amplifier, although there are as many as seven channels of output transistors(which have no amplifying ability independent of the power supply).
