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

I’m almost certain they use the exact same AKM chipset. It was listed in one of my HiFi magazines at home and am 99% certain that was it.

So I’d say SU-R1000 digital input.

I have the SU-R1000, but I wasn’t super impressed with it’s DAC at first listen. I need to do some more comparisons, but have a really good DAC as is (Zenith Steamer via USB audio to Matrix X SPIDF D2D w/LPS 9v running I2S to my Gustard X26 Pro) and have the Musetec MH-DA005 coming to trial.

Only had the SU-R1000 for a week though now.

What are your thoughts?

I have the SU-R1000, but I wasn't super impressed with it's DAC.

Probably just token Delta Sigma dac being an AKM AK5572, I think many sound cards use them.
It's more about the amp maybe with a hi-end dac feeding it.
How does it sound btw??

Every single thing I've read on the SU-G700 and SU-R1000 never mentioned either as having/using an off the shelf DAC. I believe the DAC process was conceived and done by Technics, in house.

All input signals (analog and digital) go through a ADC (Burr Brown PCM1804)and it's only before the speaker outputs is where it's converted back to analog.

Two different retailers that sell them couldn't tell me how the DAC is done except to quote Technics explanation of how they do it in general terms and that it's not an off the shelf DAC. I could be wrong but it's what I found out. 

All the best,

I'll be honest I had the SU-G700 and I believe that had a Burr Brown chipset for it's DAC, I really enjoyed the sound. Now I've had the SU-R1000 for a week, with only two listening sessions in and none of them too loud thanks to my pregnant wife. But I know it has a AKM chip, not the Burr Brown, and there absolutely is a difference.

@georgehifi more neutral then the SU-G700, that's for sure, but I also got my new speakers too so my entire system is new. Heads still spinning. Previously had a lot of enjoyable time with my KEF LS50 Meta's and SU-G700, but now have the SU-R1000 and JBL L100 Classic 75's.

All an all when I did listen straight from my streamer (Innuous Zenith) to the SU-R100 I noticed more detail, but I've honesty not given it nearly enough time to even speak about it.

I need to just get my wife out of the house and settle in to my chair and listen.
