The Bluesound Icon was stock. It is just a spare all in one unit I have whenever I need a source for testing some other gear.
Yes the Holo Audio Red has built in LPS and the CNC aluminum case is cut to encase it for shielding. You can run Volumio or Ropieee but also as Holo Red software. It is totally bare bones but sounds amazing. Simpler is better.
I have one set to dedicated Tidal Connect feeding a Holo Cyan 2 via I2S and it competes with anything else I have. Another Red is on order to replace the Eversolo T8 I returned today.
