I have an Intel i5 NUC running windows 10, now (3yrs old) I have updated the SSD to 2 TB and upped the ram to its max, 32gb. I use the Audirvana 3.5 app for playing my FLAC files, while doing computer things like browsing FB at the same time. My next step up would have to be a new PC, what would I require as a min, (in comparison to what I have now)... budget, around £1000+/-£100
