if you have a single .ape file & a .cue file its easier to burn it audio cd by using Exact Audio Copy (EAC) its a freeware

open eac

then goto tools > write cd-r

then goto file > load cue sheet - point to your .cue file

then just burn lorr

--------

i like a .ape + .cue audio src
because if the file is ripped from ori audio cd - it will still retain the silent gap between tracks like ori - we will get a duplicate cd just like the original
but these audio src are rare - unless we use emule
