We've had this disc playing up into the 90+ dB range for multiple days non-stop. So long as you have well built gear with adequate ventilation, this shouldn't pose a problem at all. It would be no different than playing very wide bandwidth music on your system. The difference here is that the system is only being fed a sweeping signal of limited bandwidth rather than a dynamic signal that is broadband in nature. While this does concentrate the energy applied to a very specific part of the spectrum at any given time, compare that to having hundreds / thousands of notes spread out all over the place in the same amount of time when playing music.
As mentioned, those with vented systems will have to pay attention to the woofer. If it looks like the woofer is going to pop out of the basket, it probably is. Back the gain down to achieve "good" throw out of the woofer, but don't drive it into "redline" right away. Bare in mind that the first five seconds of this track are silent and then it starts sweeping at 5 Hz and works its' way up.
Talking to Ayre may get you a different point of view than what i've mentioned here. I've used this on several systems and the results have always been VERY positive. Even systems that had high mileage on them. Then again, i try not to work with under-designed gear that is installed poorly. This is not to say that Ayre gear is "junk" ( NOT at all ), but that they may not want to assume liability for recommending such a procedure. I wold only add that one should use "common sense" when doing anything out of the norm with their system.
As a side note, you can use this same track to hear the reflective / all of the nodes in your room. In most installations, you'll literally hear the signal walking around the room at some points. The more that the image wanders, the more work you need in the speaker / room interphase. Sean
