I was wondering if you make a playlist of songs ripped with Apple Lossless, and burn it to a CD, will the CD be essentially identical in quality to the original CD that you ripped the songs from?
As long as you ripped the songs from a gapless CD with Apple Lossless and have your between-track gaps set to 0 in iTunes' burning preferences, you will get a gapless CD.
Of course, the only way to truly get a perfect, bit-for-bit reproduction of a CD is to do a proper rip in the Windows program Exact Audio Copy and then burn from the CUE and files generated by that process. However, for 99.9% of purposes, an iTunes-ripped Apple Lossless burn to a CD with 0 second gaps will be functionally equivalent/indistinguishable from the original.
