DAC question

I am a newbie to audio and have recently acquired the following pieces of equipment: Arcam A28 integtated amp, Arcam CD17 cd player, and Paradigm Studio 20 speakers. Overall, I am quite happy with this first system. However, I was wondering if adding a dac would be of any benefit or improve my sound quality? I was considering the Schiit Bifrost. Any comments or other equipment suggestions would be appreciated. Thanks
