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

Would I be better investing is a quality streamer and DAC?

I say yes; however, YMMV. I ripped my high quality CDs into my server/streamer and have never looked back at a CD player again, considering I had owned fairly alright CD players like McIntosh MCD 1100, Audio Research CD9, and Meitner MA-2. No regret.
