I used Rigelian with the BDP 3. It certainly was an improvement over Bipolar Bison (that’s a low bar), and it was free, but far from perfect. It didn’t recognize about half my library, I had to reboot it several times, and it’s Qobuz integration wasn’t optimal. All very frustrating and I was much happier after selling off the BDP3. I am currently very happy with the Melco N 100 and Cambridge Audio CXN 60 playing through my Bryston DAC3.
