For the BRYSTON, just download the RIGELIAN 3rd party app for a nice EZ interface, if you don’t like it’s own.
I dunno about the LUMIN,, but the BRYSTON has a linear power supply already built in.
- Linear Power Supply – not switching common to computers and other digital music players
- The BDP2 is powered by a noiseless linear power supply carefully isolated from the digital audio path and AC power circuits
I have the BRYSTON digital player/streamer, and I would also recommend its stablemate killer DAC for a great digital system.
