Intersection a stream with a DEM

I'm not sure I'm approaching this correctly as I've found nothing so far Googling.

Anyways, I'm trying to determine the slope of a stream (actually, a series of polyline segments making up a stream).  I've gone the ArcHydro route, but the results I'm getting from the assign stream slope are relative, whereas if I used a DEM they might be a bit more static.

So, my question is, what's the best way to intersect a stream (or any series of polylines) with a DEM to give the stream XYZ attributes?

Thanks again,
