I have Audacity 2.0 for Windows Vista and I’m trying to find a good combination.  I want my music and voice files to sound as though they are coming from a vacuum tube amplifier.  What I’m hunting for is a  warm, crisp, hi-fi sound.  I’m trying to figure out what equalization curves, compressors, filters to use on my files to make the sound warm as if it were coming out of a tube amplifier or radio console from the 1950s.  Here are two you tube videos that demonstrate the kind of sound I‘m looking for:  http://www.youtube.com/watch?v=Oq9tIBX4OMc

Any help would much be appreciated.
