Actually, with Amadeus you can set markers, split into tracks according to markers, and save the split files as flac all in one step -- so running your files through xAct would add a step. I think you can even set up your FLAC tags for your songs using Amadeus as well. Good to know that about xAct, but I'm trying to see what steps I need to have in my Mac workflow.
I just registered my free Amadeus demo version and was using it last night. Nice program for the money, can do pretty much everything I think, though I think I might want to stay with Wave Editor Izotope MBit+ dither.
