Hi,  
I’m sending a Pure DSD signal from my HIFI Rose 150B steamer to the PS Audio Direct Stream DAC using the USB interface. Receiving the signal it is apparently a DOP signal. I have checked the signal sent and it is a Pure DSD signal. On the DAC screen it clearly states it is a DOP signal. How do I get this right?

I tested what happened when I send a DSD signal from the PS Audio DMP (SACD) but I get the same result (DOP).

Please advise on how to get a Pure DSD signal through.

It’s right, as far as I know. That is how PSA “packages” DSD for transmission to the DAC.

Search the forum for “DOP” to learn more.

I may stand corrected.

See here:

> Hi mate See Ted’s post #14 here: The Bridge II only takes DoP not raw/native DSD (and only single rate DSD) Always good to check with Ted and easy enough to do luckily The DS’s USB and I2S inputs are the only inputs that can take double rate...

Hopefully, others will chime in.

Good luck.
