Which digital input to use? Technics SU-R1000 or Technics SL-G700


First of all let me start by saying I've been an avid reader of the forums for quite some time but this is my first thread...

I have both the Technics SU-R1000 (Integrated) and the Technics SL-G700 (CD / SACD & Streamer).

I am using a Raspberry Pi running Roopieee with audio going out through a HiFiBerry Digi+ hat (optical).

I use this for Tidal / Qobuz and also my own digitised CD library.

I know that the  SL-G700 uses a dual mono DAC circuit (AK4497 from Asahi Kasei) but I am unsure of what the SU-R1000 uses.

Question is, which input should I be utilizing?

Digital in to the streamer with analogue out to the amp
Digital in to the amp 

Any opinions appreciated!

Thank you.

Shouldn’t digital coax into the SU-G700 be the best option because it avoids the D/A conversation step from the CD Player or Streamer?  Meaning why feed an analog signal into SU-G700 just to be converted back to digital?
