The metafile is a vector format.  The problem is (as you
guessed) that you convert a vector image to a raster image.

The convert command is converting the vector image
in your PostScript file to a raster format and embedding
it in a PDF file.  (I don't know what happens if you
omit the "-density" option.  Convert may be clever enough
to perform a vector-to-vector conversion.)

I normally use either the ps2pdf or pstopdf command to
get a vector image in the PDF format.
(I don't know the difference between the two commands.)

That's a good practice, which I normally adhere to.
