Good to know you get the green light confirmation, thank you.

In the end, BCRich1 was correct; my research found that it is indeed the macOS that is not capable of sending raw DSD streams. The DSD over PCM (DoP) standard has been developed to send raw DSD in a fake PCM stream. This is why many users get an amber light as opposed to green.

Edit: Additional research reveals that if you use macOS to a UPNP device capable of DSD (which the BDA-3 is), the device will natively play at DSD.

So now i'm not 100% certain if using Audirvana on an Imac can deliver native DSD to the BDA-3 through USB. Surely someone can confirm this?

When I had my BDA-3, only GREEN lights with DSD over USB on my MacBook Pro via JRiver. 

I tried a windows laptop with jRiver and BDA-3 ASIO driver and the AMBER light illuminated for DSD 64, 128, and 256 files.

And I was never able to get YELLOW DSD lights wi5 Audirvana via my Mac book pro.   

I always thought that the Mac was only DoP not matter what software??

The BDA-3 supports Native and PCM. Not DOP seems like MAC is problem not supporting Native. As I never had a problem with an Intel NUC using Native (light green light) running Windowz via USB.

Even when PCM the bit rate supports the relative bit rate of SACD.
48, 88, 176k, etc.

I used to think it mattered too, it doesn’t as for DSD over HDMI don’t remember if it supported Native or not. That wouldn’t be a Bryston limitation but one of HDMI standard. So might vary from player to player. Mine has two options Bitstream (not supported) or PCM.

I have ripped my SACD disks to files. DSD does work with an old Allo DigiOne sig I have via SPDIF native. Have since moved on using a BR-20 which is essentially a BDA-3 with streamer and Preamp built in. The BR-20 streamer using one of the USB inputs.

I have tried several different dac streamer combo’s and come back to the Bryston BR-20 every time.
Love the sound don’t believe a word the ASR guy says. Unless you think he knows better then Stereophile and many other competent reviewers with actual backgrounds in electronics.

PS many of these answers are right in this thread start at first post and read forward.

native DSD = yellow lights

DoP DSD = green

I was never able to get yellow (native) with HDMI playing SACD

Apologies if i created any confusion with my recent posts; this whole time i was under the impression that DoP=amber and DSD=green.

All i was trying to confirm is if mac/Audirvana can output native DSD and when MN2CHFAN confirmed he had green lights on MacBook Pro via JRiver (and never able to get YELLOW DSD lights wi5 Audirvana on Mac book pro), i thought i was good to go with mac/Audirvana/native DSD/BDA-3. So now everything is in reverse!

Anyhow, thanks everyone for your help, i now have my answers :)
