>>power specific artefacts like clipping excluded

I suspect the audible difference between receiver and separates would be almost entirely power related, ie when the system was running at or near the design limits, ie when the power supply voltage is starting to droop on the power peaks and when instantaneous peaks are either starting to clip the output stages of the power amp or are being limited by upstream circuitry. That's when the fun starts and the differences between two "ruler flat" designs start to appear... and where a design which simply has enough power reserves that you aren't *at* the limits yet can have a real advantage.
