Is TRIPATH Class "T" Outdated Performance - Or Not?

Well, what I find is that although it can be done, does not mean that it increases the output power; exactly because Btl already doubles the voltage internally.

Im my amateur thoughts, Im wondering about it since class D amplifiers amplify both "sides" of the load - positive and negative sinals, and it is the reason the speaker is not connected to ground. So, does not matter if I get positive and negative from same channel, or the positive from one channel and negative from another channel...

So, I concluded that the only benefit would be channel separation. Does it make sense?
