No I haven't.
I almost posted a response, but then I didn't.
Because, I take it, that digital actually moves no air ... until it is converted to analog.I think it answers the original question...."Does analog move more air...?"
Yes it does.
Digital All the way!
I have several speakers of all kinds around my studio, the only speaker I have seen move air was a "Bass Reflex" (Ported) enclosure. Sound doesnt move air, it changes the air pressure alternating (in phase with the input signal) the pressure above and below the ambient air pressure which is around 14 psi. I do happen to think that Analog "Moves more Spirit"!
You keep saying that, but of course you are not correct. Sound moves air! Air molecules must move to form areas of compression and rarefaction, which we hear as sound. They just tend to move back and forth over the same tiny area rather quickly, so we don't otherwise sense the motion of sound in air as we do with wind (which is also caused by a difference in pressure, just on a much larger scale).
Sound is a Pressure Wave

For a stable oscillating wave, maybe. For a real world signal?
All me to describe the experiment I just performed; lacking a camera you will have to trust me. Or rather in the standard scientific method you can use the description of my experiment to repeat it yourself.
I placed a 14" tom-tom (double headed, no hole in the reso head) perpendicular to the floor. I placed a lit candle 3" from the drum head, such that the flame was centered on the drum head. I placed an omnidirectional, flat response, calibrated measurement microphone 1" horizontally displaced from the flame.
Striking the tom at moderate volume (measured peak of 117dBSPL at 3" from the reso head using a fast-response C-weighted meter), I observed up to 1" displacement of the flame tip; I further observed that the flame took up to 2 seconds to resume its undisturbed vertical orientation. This I repeated for about a dozen iterations.
Having recorded the tom hits using the microphone, I played back the recorded hits (24/44.1) through my studio monitors, which have 10" woofers in a sealed 70L box (no port). Placing the candle flame and measurement microphone in the same orientation to the woofer as the tom, I played back the recorded hits, first to rerecord them with the microphone. Using that method, I calibrated playback to the same RMS as the live hit recording, and compared the spectral analysis of the two waves. I noted that since the microphone and flame are significantly distant and off-axis to the tweeter, the recorded response varied above the limit of the woofer, about 4kHz. I consider that may have an impact on observed flame displacement.
With the playback level thus calibrated within 0.3dBRMS of the live hit, I observed similar candleflame displacement, up to only about 3/4" however. Again, I suspect the observed difference could be due to the relative lack of HF content due to the distance from the tweeter. The observed flame recovery time was similar.
Conclusion: soundwaves from a typical musical instrument can visibly and significantly displace ("move") air over a period of time longer than the fundamental oscillating frequency of the instrument (92Hz for this tom), and playback of those sounds can in a similar manner according to the limitations of the transducers used.

Trusting you is difficult, how come you dont have a camera?

So, if I can understand this (your grammar here is a bit confusing to me), a real, live instrument moves more air than a recording of the instrument?. . .
Because visual does not interest me. My daughter has a camera but she was traveling back home from DC last night.
How come you don't have a candle?
More importantly, how come you spout off on a bunch of topics with an authoritative tone when you really don't know what you are talking about?
I would say a live source moves more air than a 10" woofer; that's all I know at this point. If I had a very high quality full-range driver I expect the result might be closer.
But yes, live kills any recording. Live kills direct monitoring. VP doesn't believe that.
