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

I also ripped all of my CD's with dbPoweramp after I started streaming.  I held on to my CEC TL-5 transport for another 2 years, just looking at it sitting on the rack.  I finally sold it and moved on.  All of my CD's(about 400) are on a thumb drive inserted into the streamer.  No regrets.  I just haven't been able to just give away the CD's yet, but I'm almost there.  

Maybe I am asking a dumb question, but does this depend on the quality of the CD drive used to rip?

I think that is a great question. My research led me to Exact Audio Copy as the software because it interrogates the CD drive and does not read the data as a CD player would, but rather as a data appliance. The audio CD format does not have much error correction/detection so the app reads each sector multiple times looking for consistent results. It also compares your results with previous users to identify problematic data.

What I need is better hearing in a younger body anyone help with that?

I have a CD player that's been collecting dust for two years after I put all my CD's into a storage system.  Sound wise no difference in my system that's why the CD player hasn't been touched in two years. probably should sell it.
