I've used sonicators in a bio lab for certain types of sample preparations, I don't see how application of this technology, as described, would change the flavor of cannabis.
The desirable flavors in wine come from a variety of compounds and conditions; exposure to oxygen, "breathing" the wine, can help bring out some of these flavors as can proper storage, aging, temperature, etc. I don't know enough of the science behind wine tasting and gastronomy but sonicating as a means to accelerate the "breathing" process could make sense.
Correct me if I'm wrong, but the flavors that come from cannabis are mostly from the terpenes and desirable flavor does not come from the interaction with other molecules or compounds, so I'm not sure what sonicating would actually do.
