Digital separates or all in one music hub

My digital front end is lacking and I would like to upgrade my DAC as well as get a digital streamer. As of now I currently stream tidal with my MacBook Pro through a dragonfly cobalt into my integrated amplifier. So there is a lot of room for improvement. With that being said, would it be better to invest into a single unit such as a marantz SACD 30n or Arcam ST60 (just examples) that have everything I would want in one package. Or would I get better performance if I were to invest into a dedicated streamer, DAC, and SACD/CD player?

also how much am I really missing out on by listening through my MacBook the way that I am? Would it be worth while for me to get a less expensive streamer such as a used bluesound node while I save for something better?
