Native DSD versus DoP

I'm not sure how to quantify the differences I have heard streaming 24/192 vs. playing an SACD in DSD.  They are subtle.  One difference I noticed was in playing "The Priest" from Joni Mitchell's Ladies of the Canyon, her guitar was set further back from my speaker when playing the SACD vs. streaming the 24/192 file from Qobuz.  Perhaps this difference would not exist with a streamer that's better than my Node 130 with Teddy Pardo LPS.

Comparing other albums, high-res PCM streaming has been as good or better than my SACDs.  But I should note that I'm using a Cambridge CXU universal disc player, not a dedicated SACD player, so maybe that's comparable in SQ to my Node streamer.

fyi, if it helps. I have some similar hardware.  Optimized Ethernet, Volumio Rivo+, McIntosh MCT500, McIntosh D150, McIntosh C2300, two Mc275 amps.  I have ripped all my SACD to DSD - dsf files.  I put them on a microsd card and run them through the Volumio Rivo+ to the USB in the D150.  In addition, I can play the same SACD discs throught the DIN cable to the D150.  Also, I have the same DSD - dsf files on a usb stick that I can play through the MCT500 USB input, which goes through the DIN cable to the D150.  BTW, if you have not tried it, the user interface is easy and fast on the MCT500 using the USB stick.  For the D150, the Rivo+ encapsulates the dsf files in DoP to deliver the DSD to the D150 through USB.  The D150 shows DSD64 on the display when playing it.  My experience is that if the DAC shows DSD64 on the display and not a PCM number, then, you are getting the best quality DSD playback.  I would be hard pressed to tell the difference in a blind test between all these 3 ways to deliver DSD to my Wilson W/P 8 speakers.  Now, if I have the Rivo+ convert the dsf files to PCM and the D150 shows PCM frequency for those files, then, I believe I can tell the difference, although, I have not done blind tests to verify it. The Rivo+ also supports I2s, but, I have not tried that since the D150 does not support it.   So, bottom line, for me, there is a difference between "encapsulating DSD in DoP for delivery through USB" and actually converting DSD to PCM.  The former being the same as "Native DSD" and the latter being somewhat undesirable - but, needs to be verfied in your system.

PS.  One way to test your Pontus and DA2 with DSD is to rip you SACD to dsf files, or just buy/download dsf files from online, and feed them to each DAC for hearing tests.  For the DA2, you can use the MCT500 USB stick interface to send them through the DIN cable.  For the Pontus, if your streamer supports usb stick or microsd, or hard drive,  you can send it through that using the USB connection.

I don't notice any difference either. To me it seems like having files in DFF versus DSF. I've heard arguments saying one is better than the other, I've never heard that myself. 

Several years ago I could perceive a slight difference.  My hearing has taken a dive in the last few years so I am not going to pose as a Golden Ears any longer 

Thank you everyone for the responses.  I have to admit that I am surprised not to hear an opinion that native DSD is superior to DoP or even hi res native PCM.  @ghdprentice, what you say makes a lot of sense - there may be a difference, but it is an order of magnitude (or more) below components, component interplay, and interconnects, not to mention the quality of the source recordings.

I'm not going to sweat it and just enjoy the music (and maybe upgrade my speakers sometime in the next year).
