Metal film resistors do have a lower thermal noise figure than carbon
film.  They also have lower temp. coefficient and, of course 1% tolerance
instead of 5%.  The difference may not be audible though, depending
on the quality of the IC power amp you are using.  The lower noise figure
might be more noticeable in a low level pre-amp application.
