I use name brand discs (Sony, TDK, etc.) No generics! I prefer to trade in SHN format as I have most of my shows archived in SHN format. I am willing to trade audio format for rare shows. I am currently in the midst of reorganizing my list so that I have Source info along with disc counts for both SHN and Audio formats.All shows must be burnt DAO..No TAO! When extracting audio discs you MUST use EAC. Let's keep these copies as clean as possible.
