What the Voltage Paradigm seeks to do is call an amplifier a 'voltage source' when it refers to an amplifier that makes constant voltage into any load (i.e. doubles its power as the load impedance is cut in half).
For the benefit of others who may read this, and along the lines of my earlier post in this thread, I think it is important to clarify here that "doubles its power as the load impedance is cut in half" in this context does NOT necessarily mean that the power RATING doubles as the load impedance is cut in half.
It means simply that a voltage paradigm amplifier, as a consequence of its very low output impedance, WILL deliver twice as much power into a 4 ohm load as into an 8 ohm load, provided that it is not called upon to deliver more power than it is capable of delivering (e.g., it reaches the clipping point). And that maximum power capability will in some cases correspond to significantly less than twice the number of watts at 4 ohms as at 8 ohms.
