Our RPI Pro has an SFP fiber port and fully supports NAA, so it can act as a network audio adapter for HQPlayer.
Like the holo audio Red, RPI Pro works as a network bridge. On top of that, it comes with a high-precision oven-controlled crystal oscillator (OCXO) built in. This helps reduce jitter, providing more stable sound.
In short, it should fit your setup perfectly, combining convenience with excellent audio performance.
