Darkglass released their first comp around 9 years ago or so, its an ongoing development. Certainly not a new or recent area for them! I don't think they are hell bent on trying to conquer the compressor market, Doug just has a real passion for it, hence its constant development. This is his best yet, and undercuts many other high end pedal compressors in cost. Ultimately though, its a compressor, and unless you know how to use on effectively, you shouldn't go near one.
The B3K was upgraded this year and has far from been superseded
