Streaming Music and being able to keep them as your personel files

I wonder if it’s possible to record the Tidal digital signal off the digital output of my Esoteric DAC as Tidal streams through the DAC in real time. I have a Tascam digital recorder that should be able to pick that up from the DAC's RCA digital output and record it.  Alternatively, it's a straight-forward process to pass a DAC's analog outputs into the Tascam's ADC for recording.  However it would be nicer to avoid multiple digital-to-analog conversions by keeping the process in the digital domain.

I can confirm that a Tidal stream-- including Tidal MQA masters that decode to 24/96--  can be digitally copied from the digital output of a DAC. That's all she wrote...

@zyac39 Well, I guess I raised more questions than I answered.  Several hours after copying that file into my NAS for replay through the Roon core, the file and its folder mysteriously evaporated!  However, it still resides on the PC to which I originally transferred it from the digital recorder.  So for the moment it looks like Tidal and MQA have thought this through.  I surmise that it may be possible to keep such copies alive on a device that doesn't ping the net-- but there are precious few of those. 

Revisiting my hi-res recording of a streamed Tidal master off the digital output of a DAC, it appears that the recorded file survives intact and is playable through Roon, provided that the Tidal version of that album is not tagged to the Roon library.  We'll see if that lasts.  

Recording from Tidal or Qobuz streams in real time in the digital domain works. To complete the experience you need software like Vinyl Studio to sequence the tracks and find the metadata.
