Still on the fence regarding Roon...
This product is still a long way from production as software development will take us some time.
What I can tell you...
It will have 4 ways to connect a DAC
USB
Coaxial
Toslink
Differential I2S (over HDMI cable compatible with PS Audio, Wyred for Sound, etc.)
Will support Music Services like Tidal, Pandora, Internet Radio, etc.
Will allow connecting an external ROM drive to rip CD's to any drive on the network (.wav or .flac)
Can be connected to a network but can also work stand-alone.
Once connected, it can be it's own network to be controlled by anything with a web browser... phone, tablet, computer.
I'll provide more info as it becomes available.
