Anyone been able to compare the SQ of Roon Nucleus vs. MacBook Air?


For the last several years I've wanted to reclaim my MacBook Air laptop for laptoping! I was thinking of 2 options. Trade my Mytek Brooklyn in plus $1200.00 for a Brooklyn Bridge or spend approximately the same money for a Roon Nucleus. My laptop has been plugged into my DAC via USB. I believe the Roon Nucleus could be hooked up the same way. Anyone been able to compare the two? It would seem a dedicated device would have less noise issues and time out issues. Is there a better way to connect the MacBook Air? Would a Mac Mini offer any advantages? Any advice is always appreciated!

Thank you all for your input.
It just seems like with the Nucleus there would be less (zero maybe) restarts, less noise and the ability to stream music to other parts of the house.

Get a NUC and install ROCK it's about 1/3 the price of a Nucleus and does the same thing. It runs 24/7 unattended , installs any updates in the background and if you get a fanless one is quiet. If you want to use your mac book you certainly can.
Thank you, @docknow. In your change, there was a second variable, the playback software (iTunes replaced by Roon). That may have contributed to the sonic improvements you heard.

Thanks for pointing that out.  My post is in error.

I started a Roon trial the same day as the day I purchased the Nucleus, and installed Roon on my MBP and got used to it while I awaited delivery of the Nucleus (confirmed this by looking at my receipts).  So I had about a weeks experience with Roon on the MBP before move the Roon core license to the Nucleus.  I would also add, there was no difference I could detect in the sound quality between iTunes/BitPerfect and Roon on the MBP.
