If the OP really can’t perceive a difference between the Yamaha and the Bryston, imho he should sell off the Bryston and be done with it. I get what he is saying about brand loyalty, and I held on to the BDP3 for about a year longer than I should have because I felt the same way, but ultimately it was Bryston attitude towards the problems with their controlling software, as another poster noted, that killed my loyalty. I still use and love the DAC, which btw is the first DAC that I have encountered where the usb is not a compromise, and Bryston makes good power amps, but I will probably never buy anything from them again. The BOT was also a POS.
I tried a Roon trial with the BDP3, but my previous server couldn’t handle it. If you go the Roon route make sure that you have a lot of computing firepower. And then if you have problems down the road, I suspect you will have Roon and Bryston pointing fingers at each other
when I bought the Melco N100 my original intent was just to use it as a server with the BDP3, but the Melco dealer talked me out of it, and I’m glad he did. The Melco as a player equaled, if not exceeded, the BDP3 sonically . I haven’t tried Roon with the Melco but there is a Melco fb Forum and others seem pleased.
I used Rigelian with the BDP3. It was an improvement over Manic Moose—that is a low bar—and it was free, but it couldn’t find about half the music on server, and was unstable, leading to a lot of deletes and rebooting.
I added a SHM DSP to the system for Room Correction. It basically threw in a free streamer and said streamer sounded very thin with the DAC3. So all streamers are not created equally. However if the OP finds the Yamaha to be a good fit…
