Prof - I noted in their website talk that they are using high-order DSP filters, which do not produce phase coherence, although all the talk implies that they do.
In my music production consulting work, I routinely picked out edits in mixes by the pre and post ringing of high-order DSP filters, while listening through (coherent) CS2.2s. The producer would invariably respond that "you can't hear that", usually because of his $7 figure equipment investment and grammy awards. But I and my client could independently spot the edits and other anomalies by separately noting time-code.
I don't claim to know what Meadowlark is doing. The review I found of the Swift shows wildly ranging impedance and phase swings - but it is time-coherent. The Shearwater qualifies as a T/P coherent design.
