Dant87, I use Apple's new entry level macbook as source\streamer\player. For me, it's the perfect source and has many advantages:
1. It's 100% silent, no fans, no buzzing transformers, no spinning drives, nothing. It's passively cooled and completely silent.
2. I run it on batteries, has long battery life, which isolates it from mains electricity. Why? To stop electrical noise from mains electricity entering the DAC and degrading sound quality.
3. It has USB output which, for Chord DACS, gives the best sound quality. If you use a DAC that has galvanic isolation on USB, such as V1 or Chord Hugo TT, then your system is completely isolated from source noise (from laptop) or noise from the mains (if running on batteries and nothing else connected to laptop that is connected to mains such as ethernet cable) both of which degrade sound quality. It's also very energy efficient and low noise like an iPhone or iPad. If your DAC does not have galvanic isolation on USB then you can buy third party product that does such as Intona USB or hifime hi speed USB isolator.
4. It has bit perfect output. iTunes and other players such as Audirvana are bit perfect. I use iTunes.
5. It works seamlessly with my other mobile devices such as my iPhone. I control playback using Apple Remote app on my iPhone. I can also control playback using my watch, now that's pretty cool.
6. It's reasonably priced.
7. When I'm away from home I take it with me and use it for work!
My view is, and others may disagree, (i) if your source is fully isolated and (ii) offers bit perfect playback then you won't hear any difference. If you do hear a difference then it's due to poor DAC design, noise in the source, or not perfect playback.
The answer to your question is using a laptop will not damage the audio in any way if you heed the above advice, the data will arrive at DAC intact and bit perfect.
