Looks like Wilson are on some sort of a SAM quest. With the difference being Wilson adjusting the speaker to the amp and cables:

"Transit time can be significant when you're talking about this critical degree of time resolution, and can be ascertained using propriety techniques," he said. "In the low frequencies where many solid-state amplifiers have very close alignment, a vacuum-tube amplifier may lag by about 50 microseconds. With the WAMM's adjustability, that variable can be normalized. If we know a particular amplifier's "time profile", we can derive the appropriate custom alignment. We've looked at six different amps so far, but we are just getting started."
One pair of WAMM P2 prototypes will eventually be permanently mounted at one end of a small, narrow padded room in the Wilson factory, with a permanently affixed microphone at the other end. Here, when essential timing information is not supplied by manufacturers, Wilson Audio will measure an assortment amps and/or cables and determine their timing profiles. In cables, of special interest is the delay time in various ranges, eg, the high frequencies relatives to the upper midrange to the lower midrange and to the bass.
I fully understand that time alignment between the different frequencies can be important. But then again when you're at a concert you're most likely further away from the artists so what you hear live will be more miss aligned then what's coming from your speakers.
