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.

You are correct, it being a adc not dac my mistake.

But I’ll hold firm in that
Even the 6 x digital inputs can be accessed as analog from the "rec out rca’s"
So it can be used as a stand alone dac also.

You don’t get it. The amp is a digital amp. It takes digital signals and converts them to analog via a pcm to pwm converter (pure digital with class D PWM output stage)......this is not a DAC in the normal sense of the word.

Now there might be a cheap DAC chip in there to convert the digital inputs to analog to feed the record out rca jacks.....but that DAC chip *if such a thing exists" would have nothing to do with the amp section.   And if there is a DAC in there to do this......why the heck would you care.  You are buying this to hear a digital amp......not to use as a DAC.  It already does what a DAC does.  If you want a great DAC....the there are tons of other options.

Yes, try and cover your tracks....you had no idea how the Technics worked till I told you.
