Both the 1.6 and 3.6 measured by Stereophile showed about 83.5db/watt at 1 meter and around 4 ohms impedance. Assuming you put them in the same size room and sit the same distance away I would say they should be about the same loudness with a slight edge to the bigger 3.6 perhaps for being a better approximation to a true line source.

Can a given MMG/.7 listener happily using a *minimally* powered amp, one day decide on a 3.7i or 20.7, but continue on using this same *minimally powered amp*, or would a *higher* powered amp be required? (Same listener, same environment.)
One needn't be concerned measuring SPLs and test tone discs, etc. This given listener simply wants to have pleasant listening experiences using their usual wide variety of program material and sound sources. Assume he/she listens to pop, rock, classical and everything else under the sun. (Dealer showrooms exist to demonstrate that - potential customers don't arrive with SPL measuring equipment/test tone sources, unless they want to be 'shown the door'.)
I would say yes as long as the room and listening distance stay the same. Move to a bigger room and/or sit much further away and then it might be inadequate.
"I would say yes as long as the room and listening distance stay the same."
Well, naturally what type test (or experiment) would it be otherwise?
Still however, hearing would be believing.
