My story is much the same - loads of concert and other source material not available through streaming services on local storage, with a Qobuz subscription for high quality material. The two independent sets of material coexist seamlessly through my Roon library and I coudn't be happier with the ease of access to it all.
For those with both local storage and a streaming service subscription, I'd highly recommend trying the free Roon trial offer.
