Mike:
I think you're confusing "Build Quality" with longevity. The McIntosh is superbly built gear, and probably one of the best in the business on build quality. I HAVE heard the DK, and I have popped the top. I can tell you that the build quality on the DK is equal to the best I have seen. It's not as chunky as a McIntosh in terms of 3/4 faceplate and all, but it's built as good as anything coming out of Levinson's doors.
As far as longevity though, no one really knows, and probably no one will ever be able to take that from McIntosh.
