Soundaware USB regenerators

Make it rain – In German Regen means rain. In Soundaware lingo, it's short for regenerate, in this instance USB. The PA1-REF [$2'749] is the big version which buffers data incoming via its USB3.0 port, then regenerates it in high-speed RAM with a low phase-noise oscillator powered by super capacitors. Two smaller units with simpler power supplies are the PA1-NU [$749] to regenerate USB and Ethernet; and the PA-1 USB [$549] for just USB. Vinshine Audio have a video exploring these devices.
