I use Adaptec Jam 6, which is no longer available.
Key to disc burning software, for hard core audiophyles, is to know if the software is burning discs without any cuts or sector boundary issues at the end of tracks (DAO type stuff).
Jam 6 has been very good to me in creating custom CD's and being able to do fades, etc. on the fly while burning.
Haevn't tried Toast 10 but may, and I might look into Burn as well.
Anyone have opinion on really good audio extraction software for Mac that is similar to Exact Audio Copy (EAC) in the Windows domain?
