This is a masterpiece. It's a piece of equipment that naturally refines the sound, rather than altering it like a VCA or FET-style compressor. The appeal of analog outboard gear is the texture you can't get "In The Box," so if you're interested, please consider adding it to your setup. The power supply unit is external, not built-in, which allows for lower noise and dispersed heat, resulting in a design that considers the lifespan of the circuitry.
