Audacity is multi-platform so if you like it now, no reason to switch. Also, if you set it up to drop track markers on sector boundries, you eliminate the need for a CD Wave replacement. Check out Songbird in place of foobar. I use flac on the command line but there is something that will flac your stuff for you. A lot of this was recently discussed in the Team Mac thread over on the team/group section, might want to buzz over there and see what others think.
