Thanks for the opinions about different top woods. All I've known about tops is that they're usually spruce; I've never heard any discussion of the diiferences between Adirondack and Sitka, let alone any other alternative such as cedar.

I have gotten the general idea ~ maybe true, maybe false ~ that Adirondack spruce might be the most desirable, since it was once used almost exclusively for top-of-the-line guitars, and the alternatives have become more popular only after the Adirondack has become relatively rare and expensive.

The fact that the material used for back-and-sides is called "tonewood" sort of mitigates against serious consideration of the tonal attributes of the top wood ~ I'm sure that jumping to such a conclusion is quite wrong.
