previous generation audio lover requesting new tech needs advice

I used to listen to CDs but now am moving from the country and want to convert all my Cds to Flac. What equipment would I need to listen to the music from these files? Just so I can easily understand, from my following set up what do I not need, what should I keep and what else should I buy in order to be able to listen to these FLAC files? (Sorry for typos in the heading - no way to correct it once posted, but I hope you understood what I meant)

My current equipment;

Wadia 270 CD Player
Wadia 27 DAC
Krell KRC 3 Preamp
Krell FPB 250M Mono Amps
Totem Mani speakers

Would like to go with a little above entry level equipment - Reducing toys at this stage of my life.
