DoP (represented by a green led on the BDA-3 DAC) is just as much DSD as native DSD (represented by an amber led on the BDA-3 DAC) is; same DSD format just different method of transmitting it.
(DSD Enabled), means that its safe for the BDP to send DSD content on that interface
BDA3 Audio 2.0 - USB Audio, this is the usb connection between the BDP and the BDA
Bryston BDP Audio Device - BUC Board, this is the digital output on the back of the BDP-3, the digital AES/EBU and coax output

Thanks very much for jumping in Chris, I appreciate the informal access we have to you and James.
And thank you for clearing up what the BUC Board is, makes perfect sense now to me.
But on the primary question you haven't really answered to my satisfaction. As I mentioned in my initial post, I do know that DoP is fully DSD content, just inside a transport wrapper. I don't question for a second that what's inside is the original content. And DoP likely makes DSD transport more flexible when interfacing other manufacturers gear, just my speculation. That's all fine. But the question is: can the BDP-3 output DSD natively (not wrapped in DoP) when connected to a BDA3/3.14 directly via USB? If not, why not? I know the BDA3/3.14 can accept and process native DSD. Please ignore Roon as a factor and assume I'm using MemorableMousse...
Grandma is visiting my house and wants to give me $10 for my birthday. She is right there in front of me yet she takes it from her purse and puts it in an envelope and hands it to me. It's the same $10 bill and we're in the same room looking at each other. Why put it in an envelope?
If I can press you for one other query that has recently puzzled me. From the BDA-3.14 manual the graphic/table that lists interfaces and their protocol/bitrate capabilities it appears the USB port can handle DSD64 and DSD256 but DSD128 is not listed. This seems odd - could you comment on that?
Thanks again and Cheers!
