why does streaming from local storage sound better than the same album, at same resolution streamed from Qobuz?

No explanation nor solution.

Did you try to play Qobuz from your local library (pc or phone) ? Where you can have the stream itself or the Qobuz file locally on your SDcard/HDD?

You could either use WiFi or an otg cable/USB into your Vega, and go further upstream to look where the quality loss arrives, given it sounds equal directly send to the Dac. You could have your local file in your phone SDcard to compare, for example.

From that test you can get some data points that help you to better understand your problem.

A standard answer I have read several times: 

it could be the use of different pressings / master versions of the same record, I. E. In the Led Zep catalogue..

Best of lucks, DT
