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.

@ricevs , Thanks for clearing that up. I only looked at the specs and reviews and looked at the shots and videos of the innards, concentrating on the G700 as I intend to buy the M2 version when it finally comes out in December. 

Though there are few reviews out there, all of them speak well of them.

All the best,

@stephencowslip, addressing the original question - "  which input should I be utilizing? " ... use the SL-G700 in front of the SU-R1000.
The G700 Output has both XLR and SE output.
Use the G700 as your Network Transport as much as possible for Streaming Duty as the services would allow ( loose the Razzy ).  
@stephencowslipI'm really sorry to hear that, I just got my new turntable that has balanced XLR connections which I intend to be using on the phone MC inputs. I really hope I don't encounter anything like this, but please keep me posted on what comes of your repair.

I honestly feel my time with the g700 had me so enamored with it considering the sound Improvement compared to my previous integrated amplifier, that now the r1000 needs a little time to grow and impress me while I listen to it.

I however committed the grand audiophile / Hi-Fi sin and swapping out every single component in my whole system for all different things within a matter of a month, so I'm completely at a loss as far as what I don't like, do like, and what is responsible for what I'm hearing.

@georgehifi I always find your posts very helpful and informative regardless of whatever misspeak takes place. So thank you for your post, thank you also for clarifying everything @ricevs the knowledge level of so many people on these forums really does impress me.
Side question, so the AKM chip in the r1000 then is just part of Technics own proprietary analog to digital conversion?
I don’t think there is anything "proprietary" in the AKM A/D circuit that Technics is using. Just using the AKM chip. Of course, the power supply used and the input stage used affects the sound.......so, in that sense everyone one who uses a particular chip will have a "one of a kind....in house design".
