Well, jpeg compression, unless it's something like a #2 or 3, doesn't really do much of anything visually at one hundred percent. This was saved as a #8, which would never affect. More likely is that fact that this was produced and sharpened on a CRT (Sony Artisan) and you're probably looking at it on an LCD type of thing, which is crunchier to begin with. Then, there's also the drum scanner, which is very sharp and those cheap ol' Mamiya lenses. You could make a case for slightly less jpeg sharpening after downsizing.
