I don't think anyone is particularly bothered by your comments -- its natural to be frustrated when a query at one of the more active and knowledgeable websites doesn't get a response, but I suspect the reason is that none of the AKers who have seen your query have experience of Sonance speakers. The knowledge base here tends to be related to vintage equipment with some interest in interesting designs or value for dollar modern equipment.
And Sonance seems to me, from what I know of it, which isn't much, to be fairly middle of the road in terms of design and perhaps a cut above in terms of build quality, so its not in the cheap and cheerful category either. And then there is the built into the wall thing which is more HT than stereo.
For what it's worth, its equally difficult finding out anything about their amps -- lots of sites claiming to have info, but almost all are bait and switch. At least AK doesn't do that.
