That depends on what kind of enhancement you are looking for. Equalizer and a little reverb can take you most of the way. You could also experiment with Magnus & Smartelectronix's wonderful Ambience plug-in (free demo version). Otherwise, it is practice, practice and a good mic, of course.

I'm not into hardware solutions, but I'm sure the good people here will give good advice.
Oh, and merry xmas to you, too!
