Please provide a technical reason why you disagree? You will quickly change your mind on this topic as soon as you measure the current drawn by any broadband, push-pull amplifier. No pair will ever show an input current that exceeds the rating of a single device even though there are two. I've made this claim several times and have been met with skepticism but no one even tries to measure that input current.

Single ended, resonant LC circuits easily sustain the input current and match the output power of a push-pull pair, using one transistor. Nothing stops two from being combined so long as phase and magnitude are balanced in each stage. Since this pair operates in phase, they both conduct simultaneously, doubling input and output power capability.
