I may just be jaded, but I think the warning is a sales pitch, to warn (promote) to audiophiles the "awesome bandwidth" of the SACD. I suspect that the material on the recording will not be any burden to the equipment at all. Real music cannot delve into the bandwidth extremes of 2 HZ or 100 KH, no matter what the technology is. I say trip the switch, play at low volume to assure there is not some RF or oscillating problems, and go for the test drive. I would be surprised if equipment in the class you are describing (any of the three!) run any risk at all from too much bandwidth from this piece or the music recorded within.
