For MCH spec, nobody in the industry put up ALL channel driver power, nobody.
In general we follow a formula of 2 channel fully driven + a portion of the remaining channels (can't recall the exact formula).  This is because movie or music never have all channel driven, so the formula is more than sufficient to cover all real life situation.

Yes, they said all channel driven, that's the industry spec, we also state all channel driven.
Go measure them.  There is a formula for "All Channel Driven".
We didn't invent this, we followed the formula given by a consultant to a leading home theatre brand.
