If I rip all my CD's to flac files do I still need a CD transport?

Some folks need to work on their digital front end. After I ripped my CD's on my Zenith 3 the Transport was sold and I never looked back. 

I ripped my CDs to an Innuos Zenith MKII. My CDs sit on the shelf and will likely stay there. I sold my CD player and haven’t looked back. 

FYI, they are both digital ends.

No you don't need it.

If the EMP attack comes, better to have saved those CDs...
