Thanks, I'm making no judgement as to the different rates, just was looking for a clear answer as to the capabilities of the SU-1.
What really confuses me is the whole DoP thing with Macs that don't do native DSD. When using the SU-1 with a Mac that requires DoP, and the SU-1 connected to a DAC that can do DSD256/512... do you happen to know what would be the rate you can actually get?
Here is a snippet from the Shenzhen Audio page:

I service both PC's and Mac's in my business but honestly I do not use Macs for anything on a day to day basis
I would cull from these specs that only DSD128 can be done in DoP mode.
I personally own an SU-1 connected to a Gustard X20U DAC via I2S (HDMI)
I do have a MacBook Pro on a shelf I could try this out with. I have never listened to music on a Mac so I'm not sure what software is involved in playing DSD DFF files on a Mac.
Specifications:
Each output interface supports sampling rates:
PCM:
44.1KHz, 48KHz, 88.2KHz, 96KHz,
176.4KHz, 192KHz, 352.8KHz, 384KHz
(I2S support all sampling rate,S/PDIF support upper to 192KHz
DSD:
2.8 MHz (DSD64)-DoP, native
5.6 MHz (DSD128)-DoP, native
11.2 MHz (DSD256)-native
(I2S output support all DSD,S/PDIF,AES/EBU support DSD64 DOP mode)
Bits width:
the highest 32 bit over I2S output
The highest 24 bit over S/PDIF
Each interface electrical standards:
1.USB input socket is a standard USB-B type socket, USB power supply range 4.5V-5.1V;
2.RCA connector outputs standard S/PDIF signal,electrical level is 550mV (standard connection load),the output impedance of 75 ohms.
3.Power suppply input is AC 115V/230V,using TALEMA transformer.
