Rs151 OCM to DSD

[RalphO]

I have read and heard in reviews that the RS151 can take a PCM file and convert it to DSD. I was told to do this I should:

• On the Unit’s Touchscreen
  • Go to [Settings] → [Audio].
  • Find the “DSD Output” or “PCM to DSD” option.
  • Select the DSD rate you want (the RS151 supports up to DSD512).
  • Once enabled, all incoming PCM streams (including FLAC, streamed PCM from Qobuz/Tidal, or local files) will be upconverted to DSD internally before hitting the DAC.

However, If I press the settings icon I do not see an Audio option. There is an Audio Settings option but that does not offer either DSD Output nor PCM to DSD. There are DSD delay time and PCM delay time.

Could some one offer some guidance.

I am also trying to figure this out. I don’t see how to do this in the menu.

Maybe it’s because such a function doesn’t exist at all?

It is documented by Hifi Rose

Try going to the In/Out settings. On the output touch the little gear icon in the upper left corner and I think you will find the settings you are looking for. This is the case with the RS130, not sure it is with the 151. Good luck.

Try going to the In/Out settings. On the output, tap the little gear icon in the upper left corner, and then you will be able to see the DSD mode function.

If I follow this instruction I get 3 similar options to those shown. They are:

Native DSD
DSD over PCM
DSD to PCM

Surely I am looking for PCM to DSD?

Ralph, I am guessing here. I have a RS130 not a 151. The RS130 does not have a DAC and no analog outputs. I think The 151 does not have the PCM to DSD (DoP) feature when you use its DAC and analog outputs. However if you use the digital outputs to send the signal to an external DAC that supports DSD the 151 should do PCM to DSD. Tap the gear on one of the digital outputs like coax and see if the option appears. See page 52 of your manual.

How do I set an RS151 to Upsample PCM to DSD Analogue Out

@Woody Thank you for your inquiry about setting the RS151 to upsample PCM to DSD and output it via the analogue outputs. The RS151 supports native DSD playback through its analogue outputs, up to DSD512 (as specified in the manual). However, the RS151 itself does not include a built-in PCM → DSD upsampling function in its firmware/OS. In other words, there is no internal setting that automatically converts PCM to DSD before analogue output.

@RalphO

1. The RS151 does not natively provide an internal PCM → DSD upsampling function.
   In other words, the “PCM to DSD (DoP)” option generally does not appear in the RS151’s OS/firmware menus.

2. Settings such as Native DSD / DoP / DSD to PCM may only appear in certain digital output modes.
   As mentioned in the post, if you see these three options by tapping the gear icon in the output settings, this is most likely referring to the digital output configuration.

3. Manuals and documentation
   While some RS151 manuals or official documents mention the “PCM → DSD conversion (upsampling)” function, its availability may vary depending on the actual firmware version or hardware configuration of the model.
